Item 5.   Other Events - Recent Developments

American Shared Hospital Services (the "Company") has terminated discussions
with US Diagnostic Inc. ("USD") regarding a merger of the companies, because
USD is unable to proceed with negotiations within a reasonable time period and
on satisfactory terms.

In December 1996, the Company and USD agreed in principle to an acquisition in
which the Company's shareholders would have received $2.25 in cash for each
outstanding share.  The parties agreed in January 1997 to increase the purchase
price to $2.40 in USD common stock, to achieve pooling accounting treatment for
the transaction.

Soon thereafter, USD publicly disclosed that it was under investigation by the
Securities and Exchange Commission and NASD for various matters, which has led
to changes in USD's senior management and a significant decline in USD's stock
price.  The Company and USD subsequently announced the delay of their proposed
merger.  The Company now has determined that the merger negotiations should be
terminated, because of the continued inability of USD to proceed with
discussions.
