               AMERICAN HEALTH SERVICES CORP. ANNOUNCES FORMATION
            OF INSIGHT HEALTH SERVICES CORP. WITH MAXUM HEALTH CORP.
            --------------------------------------------------------


         NEWPORT BEACH, CALIFORNIA, February 27, 1996 -- American Health
Services Corp. ("American Health") (OTC Bulletin Board Symbol: AHTS) today
announced that it has agreed to merge with Maxum Health Corp. ("Maxum") (OTC
Bulletin Board Symbol: MXHC), to form a new medical imaging management company
called InSight Health Services Corp. ("InSight Health").  The merger agreement
provides for American Health and Maxum to merge with subsidiaries of InSight
Health, the newly formed Delaware corporation.  As a result, American Health
and Maxum will each become wholly-owned subsidiaries of InSight Health.

         Immediately upon consummation of the merger, approximately one-half of
the issued and outstanding common stock of InSight Health will be held by
former American Health stockholders, and approximately one-half will be held by
former Maxum stockholders.  In addition, in exchange for a comprehensive
program of debt and lease restructuring, General Electric Company, acting
through GE Medical Systems ("GE"), will receive non-voting preferred stock of
InSight Health, convertible into approximately 48 percent of the common stock
of InSight Health on a fully- diluted basis.  GE will also be entitled to
receive certain payments based on future performance of InSight Health.
