Primedex Health Systems Announces the Scheduling of a Special Meeting of Stockholders, The Expected Closing Date For The Radiologix Transaction and the Intention to Becomee Listed on NASDAQ

The Company has called a Special Meeting of Stockholders to be held November 15, 2006 at The Olympic Collection, 11301 Olympic Boulevard, Los Angeles, California at 9:00 a.m. Pacific Time. The primary focus of the meeting will be stockholder approval of the proposal to acquire Radiologix, Inc., the owner and operator of 69 outpatient imaging centers located in California, Maryland, New York and various other states. Other subjects of the stockholders meeting will include the proposed change of the Company's name to "Radnet, Inc." and various other matters related to the acquisition of Radiologix and its impact on the Company. Subject to stockholder approval by Primedex and Radiologix (which is also holding its stockholders meeting on November 15) and other customary closing conditions, the Company intends to close the acquisition of Radiologix on November 15.

Primedex management has determined that it is in the best interest of the Company's stockholders to apply for listing on the NASDAQ Global Market as soon as practical. The Company believes being listed on NASDAQ will create a more orderly and liquid market for the Company's securities, increase the visibility and profile of the Company and be beneficial in attracting equity research coverage. The Company believes that the closing of the Radiologix transaction and the consummation of the proposed reverse one for two stock split will assist the Company in meeting the requirements for listing on the NASDAQ Global Market.
