Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

As described in Item 2.03 below, on April 3, 2013, RadNet Management, Inc. (or the “Borrower”), a wholly owned subsidiary of RadNet, Inc. (the “Company”) entered into an amendment to its existing credit agreement. The information set forth below in Item 2.03 of this Current Report on Form 8-K is incorporated by reference into this Item 1.01.

On April 3, 2013, the Borrower entered into a First Amendment Agreement (the “Credit Agreement Amendment”), among the Borrower, the Company, certain subsidiaries and affiliates of the Borrower (the “Subsidiary Guarantors”), certain lenders, and Barclays Bank PLC, as administrative agent and collateral agent (the “Agent”).  The Credit Agreement Amendment provides for a re-pricing of the Borrower’s senior secured term loans and the borrowing of an additional $40,000,000 of senior secured term loans under the Credit and Guaranty Agreement (the “Credit Agreement”), dated as of October 10, 2012, by and among the Borrower, the Company, the Subsidiary Guarantors, the Agent, and certain lenders.

Pursuant to the Credit Agreement Amendment, the interest rate spread over LIBOR for the Borrower’s senior secured term loans has been reduced from 4.25% to 3.25% and the interest rate spread over the Agent’s alternative base rate for the Borrower’s senior secured term loans has been reduced from 3.25% to 2.25%, and the minimum LIBOR rate underlying the senior secured term loans has been reduced from 1.25% to 1.0%. In addition, the Borrower borrowed an additional $40,000,000 of senior secured term loans under the incremental facilities in the Credit Agreement. After giving effect to the new term loan borrowing, the Borrower has approximately $388.3 million of outstanding senior secured term loans under the Credit Agreement.

The other material terms of the Credit Agreement remain unchanged and are described in the Current Report on Form 8-K filed by the Company on October 12, 2012 and in the Company’s most recent Annual Report on Form 10-K filed with the SEC on March 18, 2013, as amended. A copy of the Credit Agreement Amendment is attached as Exhibit 99.1 and is incorporated by reference herein. The foregoing description of the Credit Agreement Amendment is qualified in its entirety by reference to the full text of such exhibit. 

On April 3, 2013, the Company issued a press release announcing the closing of the previously announced re-pricing of its senior secured term loan.
