     This Current Report on Form 8-K is filed by MEDICAL IMAGING CENTERS OF
AMERICA, INC., a California corporation ("MICA"), in connection with the
matters described herein.

ITEM 1.     CHANGE IN CONTROL OF REGISTRANT.

     On November 12, 1996, MICA and US Diagnostic, Inc., a Delaware
corporation, fka U.S. Diagnostic Labs, Inc. ("USD"), consummated a merger (the
"Merger") whereby USD acquired control of MICA pursuant to an Agreement and
Plan of Merger, dated as of August 1, 1996 (the "Merger Agreement"), among USD,
MICA Acquiring Corporation, a California corporation and wholly-owned
subsidiary of USD ("Merger Sub"), and MICA. Under the Merger Agreement, Merger
Sub was merged with and into MICA, whereupon the separate existence of Merger
Sub ceased and MICA became a wholly owned subsidiary of USD. Consummation of
the Merger followed approval by the shareholders of MICA at a shareholder 
meeting held on November 6, 1996.

     In connection with the Merger, each outstanding share of MICA's common
stock, no par value ("MICA Common Stock"), has been converted into the right to
receive $11.75 in cash. Each option to purchase MICA Common Stock (each a "MICA
Option") has been cancelled and each holder of a MICA Option is entitled to a
cash payment equal to the product of the total number of shares subject to the
MICA Option and the excess of $11.75 over the exercise price per share of the
MICA Common Stock subject to the MICA Option. Each warrant to purchase MICA
Common Stock (each a "MICA Warrant") has been converted into the right to
receive a payment in cash (after the warrantholder's payment of the aggregate
exercise price for the shares of MICA Common Stock subject to the MICA Warrant)
equal to the product of $11.75 and the total number of shares of MICA Common
Stock subject to the MICA Warrant. Prior to the Merger, USD did not
beneficially own, directly or indirectly, any of MICA's voting securities apart
from any beneficial ownership interest it may have had as a result of entering
into the Merger Agreement.

     Pursuant to the Merger Agreement, members of MICA's Board of Directors
will resign and be replaced by designees of USD. MICA does not anticipate that
any officers or directors of MICA will become officers or directors of USD or
the surviving entity.

     The foregoing summary of the terms of the Merger Agreement and the Merger
does not purport to be complete and is qualified in its entirety by reference
to the full text of the Merger Agreement, a copy of which is attached hereto as
Exhibit 2.1 and incorporated herein by reference.

     On November 12, 1996, MICA and USD issued a press release relating to the
Merger, a copy of which is attached hereto as Exhibit 99.1 and incorporated by
reference.
