      Primedex Health Systems, Inc. (OTCBB:PMDX) announced today that its 
      stockholders have approved the company's acquisition of Radiologix, Inc. 
      (AMEX:RGX), which is scheduled to close later today. Primedex will 
      acquire Radiologix in a cash and stock transaction valued at the time of 
      announcement on July 7, 2006, at approximately $208 million, including 
      net debt. With 134 locations throughout the United States, the combined 
      company will be the largest owner and operator of fixed-site diagnostic 
      imaging centers in the United States. After the acquisition, Primedex 
      will have 83 centers in California, 31 centers in Maryland, 12 centers 
      in New York and 8 centers in other states, including Florida, Kansas, 
      Colorado and Minnesota.

      headquartered in Dallas, Texas, allows Primedex to expand its presence 
      in California, and gives Primedex a concentrated platform outside of 
      California that it plans to optimize and grow. Primedex will use the 
      acquisition to further its strategies of geographic clustering, 
      exclusive capitation contracting and multi-modality product offerings, 
      which it will now be able to pursue on a national scale.

        31, 2006
