Item 5.    OTHER EVENTS

On March 30, 1998, the Company entered into a definitive agreement to sell
certain non-core assets, specifically the Company's mobile subsidiary Medical
Diagnostics, Inc. ("MDI") to Alliance Imaging Inc. for $35.6 million in cash,
including assumption of debt. The agreement, which is subject to
Hart-Scott-Rodino clearance, is expected to close in May 1998. The proceeds of
the sale will be used to reduce the Company's debt and to bolster the Company's
cash reserves, which have been negatively affected by the events of 1997. Mobile
imaging operations do not conform with the Company's core business of fixed site
MRI and mutimodality imaging centers.
