Accounting Policies [Abstract]
REVENUES	REVENUES - Our revenues generally relate to net patient fees received from various payors and patients themselves under contracts in which our performance obligations are to provide diagnostic services to the patients. Revenues are recorded during the period when our obligations to provide diagnostic services are satisfied. Our performance obligations for diagnostic services are generally satisfied over a period of less than one day. The contractual relationships with patients, in most cases, also involve a third-party payor (Medicare, Medicaid, managed care health plans and commercial insurance companies, including plans offered through the health insurance exchanges) and the fees for the services provided are dependent upon the terms provided by Medicare and Medicaid, or negotiated with managed care health plans and commercial insurance companies. The payment arrangements with third-party payors for the services we provide to the related patients typically specify payments at amounts less than our standard charges and generally provide for payments based upon predetermined rates per diagnostic services or discounted fee-for-service rates. Management continually reviews the contractual estimation process to consider and incorporate updates to laws and regulations and the frequent changes in managed care contractual terms resulting from contract renegotiations and renewals. As it relates to the Consolidated Medical Group, this service fee revenue includes payments for both the professional medical interpretation revenue recognized by the Consolidated Medical Group as well as the payment for all other aspects related to our providing the imaging services, for which we earn management fees. As it relates to other centers, this service fee revenue is earned through providing the use of our diagnostic imaging equipment and the provision of technical services as well as providing administration services such as clerical and administrative personnel, bookkeeping and accounting services, billing and collection, provision of medical and office supplies, secretarial, reception and transcription services, maintenance of medical records, and advertising, marketing and promotional activities. Our service fee revenue is based upon the estimated amounts we expect to be entitled to receive from patients and third-party payors. Estimates of contractual allowances under managed care and commercial insurance plans are based upon the payment terms specified in the related contractual agreements. Revenue related to uninsured patients and copayment and deductible amounts for patients who have health care coverage may have discounts applied (uninsured discounts and contractual discounts). We also record estimated implicit price concessions (based primarily on historical collection experience) related to uninsured accounts to record self-pay revenue at the estimated amounts we expect to collect. Under capitation arrangements with various health plans, we earn a per-enrollee amount each month for making available diagnostic imaging services to all plan enrollees under the capitation arrangement. Revenue under capitation arrangements is recognized in the period in which we are obligated to provide services to plan enrollees under contracts with various health plans.
EQUITY BASED COMPENSATION	EQUITY BASED COMPENSATION – We have one long-term incentive plan, which has been amended and restated on April 20, 2015, March 9, 2017, April 15, 2021, April 27, 2023, and most recently following approval by our stockholders at our annual stockholders meeting on June 7, 2023 (the “Restated Plan”). We have reserved 20,100,000 shares of common stock for issuance under the Restated Plan which can be issued in the form of incentive and/or nonstatutory stock options, restricted and/or unrestricted stock, stock units, and stock appreciation rights. Terms and conditions of awards can be direct grants or based on achieving a performance metric. We evaluate performance-based awards to determine if it is probable that the vesting conditions will be met. We also consider probability of achievement of performance conditions when determining expense recognition. For the awards where vesting is probable, equity-based compensation is recognized over the related vesting period. Stock options generally vest over three years to five years and expire five years to ten years from date of grant. We determine the compensation expense for each stock option award using the Black Scholes, binomial lattice valuation or similar, valuation model. Those models require that our management make certain estimates concerning risk-free interest rates and volatility in the trading price of our common stock. The compensation expense recognized for all equity-based awards is recognized over the service periods. Equity-based compensation is classified in operating expenses within the same line item as the majority of the cash compensation paid to employees. In connection with our acquisition of DeepHealth Inc. on June 1, 2020, we assumed the DeepHealth, Inc. 2017 Equity Incentive Plan, including outstanding options awards that can be exercised for our common stock (the "DeepHealth options"). No additional awards will be granted under the DeepHealth, Inc. 2017 Equity Incentive Plan. In connection with our acquisition of iCAD, Inc. on July 17, 2025, we assumed the iCAD, Inc. 2016 Stock Incentive Plan, as amended, and the iCAD, Inc. 2012 Stock Incentive Plan, as amended by Amendment No. 1 (collectively, the “iCAD Plans”), including outstanding option awards that became exercisable for shares of our common stock. No additional awards will be granted under the iCAD Plans.
ACCOUNTS RECEIVABLE	ACCOUNTS RECEIVABLE - The vast majority of our accounts receivable are due under fee-for-service contracts from third-party payors, such as insurance companies and government-sponsored healthcare programs, or directly from patients. Services are generally provided pursuant to one-year contracts with payors. We continuously monitor collections from our payors and maintain an allowance for bad debts based upon specific payor collection issues that we have identified and our historical experience. We have entered into factoring agreements with various institutions and sold certain accounts receivable under non-recourse agreements in exchange for notes receivable from the buyers. These transactions are accounted for as a reduction in accounts receivable as the agreements transfer effective control over and risk related to the receivables to the buyers. Proceeds on factoring agreements are reflected as operating activities on our statement of cash flows and on our balance sheet as prepaid expenses and other current assets for the current portion and deposits and other for the long-term portion. Amounts remaining to be collected on these agreements were $2.6 million and $3.5 million at March 31, 2026 and December 31, 2025, respectively. We do not utilize factoring arrangements as an integral part of our financing for working capital and assess the party's ability to pay upfront at the inception of the notes receivable and subsequently by reviewing their financial statements annually and reassessing any insolvency risk on a periodic basis.
DEFERRED FINANCING COSTS	DEFERRED FINANCING COSTS - Costs of financing are deferred and amortized using the effective interest rate method and are related to our revolving credit facilities.
PROPERTY AND EQUIPMENT	PROPERTY AND EQUIPMENT - Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization of property and equipment are provided using the straight-line method over their estimated useful lives, which range from 3 to 15 years. Leasehold improvements are amortized at the lesser of lease term or their estimated useful lives, which range from 3 to 15 years. Maintenance and repairs are charged to expense as incurred.
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS - When the qualifications for business combination accounting treatment are met, it requires us to recognize, separately from goodwill, the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations. Acquisition-related costs are expensed as incurred and are included in Cost of operations, excluding depreciation and amortization, in the condensed consolidated statements of operations.
GOODWILL	GOODWILLGoodwill is recorded as a result of business combinations. If we determine the carrying value of a reporting unit exceeds its fair value an impairment charge would be recognized and should not exceed the total amount of goodwill allocated to that reporting unit. We tested goodwill and indefinite lived intangibles for impairment on October 1, 2025 noting no impairment, and we have not identified any indicators of impairment through March 31, 2026.
INCOME TAXES	INCOME TAXES - Income tax expense is computed using an asset and liability method and using expected annual effective tax rates. Under this method, deferred income tax assets and liabilities result from temporary differences in the financial reporting bases and the income tax reporting bases of assets and liabilities. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefit that, based on available evidence, is not expected to be realized. When it appears more likely than not that deferred taxes will not be realized, a valuation allowance is recorded to reduce the deferred tax asset to its estimated realizable value. For net deferred tax assets, we consider estimates of future taxable income in determining whether our net deferred tax assets are more likely than not to be realized. On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law, which enacts significant changes to the U.S. Tax and related laws. Some of the provisions of the new tax law that affect corporations include, but are not limited to, reinstatement of immediate expensing of domestic specified research or experimental expenditures, restoration of EBITDA as the base for calculating deductible business interest expense, modifications to international tax regimes, and reenactment of one hundred percent bonus depreciation on eligible property acquired after January 19, 2025. The impact of the tax law changes from OBBBA with respect to periods prior to enactment were recognized by the Company in the third quarter of 2025, and has been applied prospectively based on the effective dates of the tax law. The enactment of the OBBBA did not have a material impact on the Company’s financial statements. In 2021, the Organization for Economic Co-operation and Development ("OECD") announced an inclusive framework on base erosion and profit shifting including Pillar Two Model Rules defining the global minimum tax, which calls for taxation of large multinational corporations at a minimum rate of 15%. Subsequently, multiple sets of administrative guidance have been issued. Many non-US tax jurisdictions have either recently enacted legislation to support certain components of Pillar Two Model Rules beginning 2024 (including the European Union Member States) with the adoption of additional components in later years or announced their plans to enact legislation in future years. Though the model rules provide a framework for applying the minimum tax, countries may enact Pillar Two Model Rules slightly differently than the model rules and on different timelines and may adjust domestic tax incentives in response to Pillar Two Model Rules. On a long-term basis, we will continue to evaluate the impacts of enacted legislation and pending legislation to enact Pillar Two Model Rules in all countries applicable to us. For 2026, we expect that we will meet one or more transactional safe harbor rules, and as such, we do not believe Pillar Two model will have an impact on our annual effective tax rate for the year ending December 31, 2026.
LEASES	LEASES - We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and long-term operating lease liability in our condensed consolidated balance sheets. Finance leases are included in property and equipment, accounts payable, accrued expenses and other, and long-term finance lease liability in our consolidated balance sheets. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. We include options to extend a lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For a contract in which we are a lessee that contains fixed payments for both lease and non-lease components, we have elected to account for the components as a single lease component. ROU assets are tested for impairment if circumstances suggest that the carrying amount may not be recoverable. Our ROU assets consist of facility and equipment assets on operating leases. No events have occurred such as fire, flood, or other acts which have impaired the integrity of our ROU assets as of March 31, 2026. Our facility leases require us to maintain insurance policies which would cover major damage to our facilities. We maintain business interruption insurance to cover loss of business due to a facility becoming non-operational under certain circumstances. Our equipment leases are covered by warranty and service contracts which cover repairs and provide regular maintenance to keep the equipment in functioning order. We closely monitor patient levels at our imaging centers and occasionally divest or shut down centers to maximize utilization rates. We may abandon low utilization leases and divert the patients to nearby centers. During the three months ended March 31, 2025, we closed several imaging centers with lower utilization and recognized lease abandonment charges of approximately $5.4 million in our Imaging Center segment. Of these amounts, $4.8 million were related to right-of-use assets impairment and $0.6 million were related to the write-off of leasehold improvements for the three months ended March 31, 2025.
COMPREHENSIVE LOSS	COMPREHENSIVE LOSS - Accounting guidance establishes rules for reporting and displaying other comprehensive income (loss) ("OCI") and its components. Our foreign currency translation adjustments and the amortization of balances associated with derivatives previously classified as cash flow hedges are included in OCI. The components of OCI for the three months ended March 31, 2026 and 2025 are included in the Condensed Consolidated Statements of Comprehensive Loss.
INTEREST ON SECURITIES	INTEREST ON SECURITIES - We recognized income from interest on securities of approximately $5.0 million and $7.7 million for the three months ended March 31, 2026 and 2025, respectively. This income is recorded within Other non-operating income in our Condensed Consolidated Statements of Operations.
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES - We are party to various legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. With respect to these matters, we evaluate the developments on a regular basis and accrue a liability when we believe a loss is probable and the amount can be reasonably estimated. Based on current information, we do not believe that reasonably possible or probable losses associated with pending legal proceedings would either individually or in the aggregate, have a material adverse effect on our business and consolidated financial statements. However, the outcome of these matters is inherently uncertain. Therefore, if one or more of these matters were resolved against us for amounts in excess of management's expectations, our results of operations and financial condition, including in a particular reporting period in which any such outcome becomes probable and estimable, could be materially adversely affected.
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS – Assets and liabilities subject to fair value measurements are required to be disclosed within a fair value hierarchy. The fair value hierarchy ranks the quality and reliability of inputs used to determine fair value. Accordingly, assets and liabilities carried at, or permitted to be carried at, fair value are classified within the fair value hierarchy in one of the following categories based on the lowest level input that is significant to a fair value measurement: Level 1—Fair value is determined by using unadjusted quoted prices that are available in active markets for identical assets and liabilities. Level 2—Fair value is determined by using inputs other than Level 1 quoted prices that are directly or indirectly observable. Inputs can include quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets and liabilities in inactive markets. Related inputs can also include those used in valuation or other pricing models such as interest rates and yield curves that can be corroborated by observable market data. Level 3—Fair value is determined by using inputs that are unobservable and not corroborated by market data. Use of these inputs involves significant and subjective judgment. We consider the carrying amounts of cash and cash equivalents, receivables, other current assets, and current liabilities to approximate their fair value because of the relatively short period of time between the origination of these instruments and their expected realization or payment. Additionally, we consider the carrying amount of our notes payable to approximate their fair value because the weighted average interest rate used to formulate the carrying amounts approximates current market rates.
EARNINGS PER SHARE	EARNINGS PER SHARE - Earnings per share is based upon the weighted average number of shares of common stock and common stock equivalents outstanding, net of common stock held in treasury, as follows (in thousands except share and per share data):
INVESTMENTS IN EQUITY SECURITIES	INVESTMENTS IN EQUITY SECURITIES–Accounting guidance requires entities to measure equity investments at fair value, with any changes in fair value recognized in net income. If there is no readily determinable fair value, the guidance allows entities the ability to measure investments at cost, adjusted for observable price changes and impairments, with changes recognized in net income.
INVESTMENTS IN JOINT VENTURES	INVESTMENT IN JOINT VENTURES – As of March 31, 2026, we have 12 unconsolidated joint ventures operating 50 diagnostic imaging centers that represent partnerships with hospitals, or health systems and were formed for the purpose of owning and operating diagnostic imaging centers. Professional services at the joint venture diagnostic imaging centers are performed by contracted radiology practices or a radiology practice that participates in the joint venture. Our investment in these joint ventures is accounted for under the equity method, as we do not have a controlling financial interest in such ventures. We evaluate our investment in joint ventures, including cost in excess of book value (equity method goodwill) for impairment whenever indicators of impairment exist. No indicators of impairment existed as of March 31, 2026 and December 31, 2025.
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	Recently Issued Accounting Pronouncements In November 2024, the FASB issued Accounting Standards Update ("ASU") 2024-03 (“ASU 2024-03”), Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, to enhance the transparency of certain expense disclosures. The amendments in this Update require disclosure of specific expense categories in the notes to the financial statements for both interim and annual reporting periods. The Update also requires disaggregated information about certain prescribed expense categories underlying any relevant income statement expense caption. The amendments in this Update are effective for public entities for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted, and the amendments may be adopted either prospectively or retrospectively. We are currently evaluating the impact of this ASU on our consolidated financial statements. In September 2025, the FASB issued ASU 2025-06 (“ASU 2025-06”), Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, to modernize the accounting for software development costs and enhance the operability of the guidance for different development methods. The amendments remove the prescriptive “project-stage” model and require capitalization of software costs once management has authorized and committed to funding a project and it is probable that the software will be completed and used as intended. The Update also introduces the concept of “significant development uncertainty,” requires application of the property, plant and equipment disclosure requirements to capitalized internal-use software costs, and incorporates website development guidance into Subtopic 350-40. The amendments are effective for annual periods beginning after December 15, 2027, and interim periods within those annual periods. Early adoption is permitted. We are currently evaluating the impact of this ASU on our consolidated financial statements.

Our service fee revenue is based upon the estimated amounts we expect to be entitled to receive from patients and third-party payors. Estimates of contractual allowances under managed care and commercial insurance plans are based upon the payment terms specified in the related contractual agreements. Revenue related to uninsured patients and copayment and deductible amounts for patients who have health care coverage may have discounts applied (uninsured discounts and contractual discounts). We also record estimated implicit price concessions (based primarily on historical collection experience) related to uninsured accounts to record self-pay revenue at the estimated amounts we expect to collect.

Under capitation arrangements with various health plans, we earn a per-enrollee amount each month for making available diagnostic imaging services to all plan enrollees under the capitation arrangement. Revenue under capitation arrangements is recognized in the period in which we are obligated to provide services to plan enrollees under contracts with various health plans.

EQUITY BASED COMPENSATION

EQUITY BASED COMPENSATION – We have one long-term incentive plan, which has been amended and restated on April 20, 2015, March 9, 2017, April 15, 2021, April 27, 2023, and most recently following approval by our stockholders at our annual stockholders meeting on June 7, 2023 (the “Restated Plan”). We have reserved 20,100,000 shares of common stock for issuance under the Restated Plan which can be issued in the form of incentive and/or nonstatutory stock options, restricted and/or unrestricted stock, stock units, and stock appreciation rights. Terms and conditions of awards can be direct grants or based on achieving a performance metric. We evaluate performance-based awards to determine if it is probable that the vesting conditions will be met. We also consider probability of achievement of performance conditions when determining expense recognition. For the awards where vesting is probable, equity-based compensation is recognized over the related vesting period. Stock options generally vest over three years to five years and expire five years to ten years from date of grant. We determine the compensation expense for each stock option award using the Black Scholes, binomial lattice valuation or similar, valuation model. Those models require that our management make certain estimates concerning risk-free interest rates and volatility in the trading price of our common stock. The compensation expense recognized for all equity-based awards is recognized over the service periods. Equity-based compensation is classified in operating expenses within the same line item as the majority of the cash compensation paid to employees.

In connection with our acquisition of DeepHealth Inc. on June 1, 2020, we assumed the DeepHealth, Inc. 2017 Equity Incentive Plan, including outstanding options awards that can be exercised for our common stock (the "DeepHealth options"). No additional awards will be granted under the DeepHealth, Inc. 2017 Equity Incentive Plan.

In connection with our acquisition of iCAD, Inc. on July 17, 2025, we assumed the iCAD, Inc. 2016 Stock Incentive Plan, as amended, and the iCAD, Inc. 2012 Stock Incentive Plan, as amended by Amendment No. 1 (collectively, the “iCAD Plans”), including outstanding option awards that became exercisable for shares of our common stock. No additional awards will be granted under the iCAD Plans.

ACCOUNTS RECEIVABLE

ACCOUNTS RECEIVABLE - The vast majority of our accounts receivable are due under fee-for-service contracts from third-party payors, such as insurance companies and government-sponsored healthcare programs, or directly from patients. Services are generally provided pursuant to one-year contracts with payors. We continuously monitor collections from our payors and maintain an allowance for bad debts based upon specific payor collection issues that we have identified and our historical experience.

DEFERRED FINANCING COSTS

DEFERRED FINANCING COSTS - Costs of financing are deferred and amortized using the effective interest rate method and are related to our revolving credit facilities.

PROPERTY AND EQUIPMENT

PROPERTY AND EQUIPMENT - Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization of property and equipment are provided using the straight-line method over their estimated useful lives, which range from 3 to 15 years. Leasehold improvements are amortized at the lesser of lease term or their estimated useful lives, which range from 3 to 15 years. Maintenance and repairs are charged to expense as incurred.

GOODWILL

GOODWILLGoodwill is recorded as a result of business combinations. If we determine the carrying value of a reporting unit exceeds its fair value an impairment charge would be recognized and should not exceed the total amount of goodwill allocated to that reporting unit. We tested goodwill and indefinite lived intangibles for impairment on October 1, 2025 noting no impairment, and we have not identified any indicators of impairment through March 31, 2026.

On a long-term basis, we will continue to evaluate the impacts of enacted legislation and pending legislation to enact Pillar Two Model Rules in all countries applicable to us. For 2026, we expect that we will meet one or more transactional safe harbor rules, and as such, we do not believe Pillar Two model will have an impact on our annual effective tax rate for the year ending December 31, 2026.

LEASES

LEASES - We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and long-term operating lease liability in our condensed consolidated balance sheets. Finance leases are included in property and equipment, accounts payable, accrued expenses and other, and long-term finance lease liability in our consolidated balance sheets. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term.

For a contract in which we are a lessee that contains fixed payments for both lease and non-lease components, we have elected to account for the components as a single lease component.

ROU assets are tested for impairment if circumstances suggest that the carrying amount may not be recoverable. Our ROU assets consist of facility and equipment assets on operating leases. No events have occurred such as fire, flood, or other acts which have impaired the integrity of our ROU assets as of March 31, 2026. Our facility leases require us to maintain insurance policies which would cover major damage to our facilities. We maintain business interruption insurance to cover loss of business due to a facility becoming non-operational under certain circumstances. Our equipment leases are covered by warranty and service contracts which cover repairs and provide regular maintenance to keep the equipment in functioning order.

We closely monitor patient levels at our imaging centers and occasionally divest or shut down centers to maximize utilization rates.

Of these amounts, $4.8 million were related to right-of-use assets impairment and $0.6 million were related to the write-off of leasehold improvements for the three months ended March 31, 2025.

COMPREHENSIVE LOSS

COMPREHENSIVE LOSS - Accounting guidance establishes rules for reporting and displaying other comprehensive income (loss) ("OCI") and its components. Our foreign currency translation adjustments and the amortization of balances associated with derivatives previously classified as cash flow hedges are included in OCI. The components of OCI for the three months ended March 31, 2026 and 2025 are included in the Condensed Consolidated Statements of Comprehensive Loss.

INTEREST ON SECURITIES

INTEREST ON SECURITIES - We recognized income from interest on securities of approximately $5.0 million and $7.7 million for the three months ended March 31, 2026 and 2025, respectively. This income is recorded within Other non-operating income in our Condensed Consolidated Statements of Operations.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES - We are party to various legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. With respect to these matters, we evaluate the developments on a regular basis and accrue a liability when we believe a loss is probable and the amount can be reasonably estimated. Based on current information, we do not believe that reasonably possible or probable losses associated with pending legal proceedings would either individually or in the aggregate, have a material adverse effect on our business and consolidated financial statements. However, the outcome of these matters is inherently uncertain. Therefore, if one or more of these matters were resolved against us for amounts in excess of management's expectations, our results of operations and financial condition, including in a particular reporting period in which any such outcome becomes probable and estimable, could be materially adversely affected.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS – Assets and liabilities subject to fair value measurements are required to be disclosed within a fair value hierarchy. The fair value hierarchy ranks the quality and reliability of inputs used to determine fair value. Accordingly, assets and liabilities carried at, or permitted to be carried at, fair value are classified within the fair value hierarchy in one of the following categories based on the lowest level input that is significant to a fair value measurement:

Level 1—Fair value is determined by using unadjusted quoted prices that are available in active markets for identical assets and liabilities.

Level 2—Fair value is determined by using inputs other than Level 1 quoted prices that are directly or indirectly observable. Inputs can include quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets and liabilities in inactive markets. Related inputs can also include those used in valuation or other pricing models such as interest rates and yield curves that can be corroborated by observable market data.

Level 3—Fair value is determined by using inputs that are unobservable and not corroborated by market data. Use of these inputs involves significant and subjective judgment.

We consider the carrying amounts of cash and cash equivalents, receivables, other current assets, and current liabilities to approximate their fair value because of the relatively short period of time between the origination of these instruments and their expected realization or payment. Additionally, we consider the carrying amount of our notes payable to approximate their fair value because the weighted average interest rate used to formulate the carrying amounts approximates current market rates.

EARNINGS PER SHARE

EARNINGS PER SHARE - Earnings per share is based upon the weighted average number of shares of common stock and common stock equivalents outstanding, net of common stock held in treasury, as follows (in thousands except share and per share data):

INVESTMENTS IN EQUITY SECURITIES

INVESTMENTS IN EQUITY SECURITIES–Accounting guidance requires entities to measure equity investments at fair value, with any changes in fair value recognized in net income. If there is no readily determinable fair value, the guidance allows entities the ability to measure investments at cost, adjusted for observable price changes and impairments, with changes recognized in net income.

INVESTMENTS IN JOINT VENTURES

INVESTMENT IN JOINT VENTURES – As of March 31, 2026, we have 12 unconsolidated joint ventures operating 50 diagnostic imaging centers that represent partnerships with hospitals, or health systems and were formed for the purpose of owning and operating diagnostic imaging centers. Professional services at the joint venture diagnostic imaging centers are performed by contracted radiology practices or a radiology practice that participates in the joint venture. Our investment in these joint ventures is accounted for under the equity method, as we do not have a controlling financial interest in such ventures. We evaluate our investment in joint ventures, including cost in excess of book value (equity method goodwill) for impairment whenever indicators of impairment exist. No indicators of impairment existed as of March 31, 2026 and December 31, 2025.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Recently Issued Accounting Pronouncements

In November 2024, the FASB issued Accounting Standards Update ("ASU") 2024-03 (“ASU 2024-03”), Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, to enhance the transparency of certain expense disclosures. The amendments in this Update require disclosure of specific expense categories in the notes to the financial statements for both interim and annual reporting periods. The Update also requires disaggregated information about certain prescribed expense categories underlying any relevant income statement expense caption. The amendments in this Update are effective for public entities for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted, and the amendments may be adopted either prospectively or retrospectively. We are currently evaluating the impact of this ASU on our consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06 (“ASU 2025-06”), Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, to modernize the accounting for software development costs and enhance the operability of the guidance for different development methods. The amendments remove the prescriptive “project-stage” model and require capitalization of software costs once management has authorized and committed to funding a project and it is probable that the software will be completed and used as intended. The Update also introduces the concept of “significant development uncertainty,” requires application of the property, plant and equipment disclosure requirements to capitalized internal-use software costs, and incorporates website development guidance into Subtopic 350-40. The amendments are effective for annual periods beginning after December 15, 2027, and interim periods within those annual periods. Early adoption is permitted.
