We have acted as counsel to RadNet, Inc., a Delaware corporation (the “Company”), in connection with the filing of the Prospectus Supplement, dated January 30, 2026 (the “Prospectus Supplement”), to the Registration Statement on Form S-3 (File No. 333-291945) filed with the Securities and Exchange Commission (the “Commission”) on December 4, 2025 under the Securities Act of 1933, as amended (the “Securities Act”). The Prospectus Supplement relates to the registration for the offer and resale by the selling stockholders named in the Prospectus Supplement (the “Selling Stockholders”) of up to 190,924 shares of the Company’s common stock, par value $0.0001 per share, to be issued to the Selling Stockholders or their respective designees (the “Shares”), pursuant to the Share Purchase Agreement, dated November 10, 2025, by and among the Selling Stockholders, which are listed in Schedule 1 therein, and the Company’s wholly-owned subsidiary, DH AI International Holdings, B.V., a company incorporated in the Netherlands (the “SPA”).
This opinion letter is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

This opinion is based solely on the General Corporation Law of the State of Delaware (including all related provisions of the Delaware Constitution and all reported judicial decisions interpreting the General Corporation Law of the State of Delaware and the Delaware Constitution).
Based upon and subject to the foregoing, we are of the opinion that the Shares have been duly authorized for issuance, and when issued and delivered by the Company pursuant to SPA, will be validly issued, fully paid and nonassessable.
