                 INSIGHT HEALTH SERVICES ANNOUNCES $25 MILLION EQUITY
                           INVESTMENT BY THE CARLYLE GROUP

       --INVESTMENT IS PART OF $150 MILLION CAPITAL INFUSION TO FUEL GROWTH --

    Newport Beach, CA, October 14, 1997 - InSight Health Services Corp.
(NASDAQ: IHSC) today announced a major capital infusion, which includes the
purchase by The Carlyle Group of $25 million in new Preferred Stock at $8.38 per
share.  Simultaneously, InSight has executed a definitive agreement with
NationsBank, N.A. for $125 million in senior secured credit financing.  In
addition, InSight has created a new class of Preferred Stock, part of which has
been issued to GE in exchange for the early buyout of its supplemental service
fee arrangement with InSight, and the balance of which is expected to be issued
to GE shortly in exchange for its existing Series A Preferred Stock.  The
Company's Board will be expanded to nine members.  As a result of their
investment in InSight, Carlyle and GE have received the right to appoint two
directors, and one director, respectively.

    Frank E. Egger, InSight's Chairman of the Board stated, "This capital
infusion is strong evidence of The Carlyle Group's and GE's support for this
management team and the long-term strategic direction InSight is pursuing.  It
places the Company in a significantly stronger financial position from which to
execute its business plan.  It also enhances InSight's ability to maximize
shareholder value."
    E. Larry Atkins, InSight's President and Chief Executive Officer added,
"This capital infusion is an enormous step forward for InSight - one that
substantially boosts our resources, lowers our cost of capital and fuels our
future growth.  We are in the midst of several growth initiatives, including
acquisitions, expansion of open MRI units and continued development of our
radiology co-sourcing product.  All these programs will be supported from a
stronger capital base as a result of this investment.  We are delighted to be
associated with organizations of Carlyle's, NationsBank's and GE's caliber.  The
conversion price of the new Preferred Stock is at a supplemental premium to the
recent trading price of our Common Stock, which we believe is a real vote of
confidence from these organizations."

NATIONSBANK CREDIT AGREEMENT

    The $125 million NationsBank financing will include a term loan designed to
refinance existing debt, a working capital facility and an acquisition facility.
The working capital and acquisition facilities will result in $75 million of new
capacity to fuel growth and acquisitions.  These senior credit facilities will
result in a two hundred basis point reduction in current interest rate costs
over the refinanced debt.  Funding is subject to the satisfaction of certain
customary conditions and is expected to occur within two weeks.

THE CONVERTIBLE SECURITIES
     As part of the transaction, GE has agreed to convert all of its existing 
non-voting Series A Preferred Stock into the new Series C Preferred Stock 
upon expiration or earlier termination of the 30-day waiting period under the 
Hart-Scott-Rodino Antitrust Improvements Act.  GE has also received 835,821 
shares of Series C Preferred Stock in exchange for the early cancellation of 
the supplemental service fee agreement, thereby eliminating InSight's annual 
expense representing a fourteen percent pretax income payment to GE.  This 
termination will result in a non-recurring expense of approximately $6.7 
million in the second quarter of fiscal 1998.  When converted, GE's holdings 
would represent 34 percent of the current fully-diluted outstanding shares, 
and has an initial conversion price of $8.38 per share of Common Stock.  GE 
has also acquired warrants to purchase 250,000 shares of InSight Common Stock 
at an initial exercise price of $10.00 per share.
    The Series B Preferred Stock purchased by Carlyle will be convertible
initially into an aggregate of 2,985,075 shares of InSight Common Stock, or 31
percent of the fully-diluted outstanding shares, at an initial conversion price
of $8.38 per share of Common Stock.  Carlyle has also acquired warrants to
purchase 250,000 shares of InSight Common Stock at an initial exercise price of
$10.00 per share.

    The new Preferred will vote with the Common Stock on all matters except the

37 percent of the votes eligible to be cast on such matters.  The Series  B and
the Series C Preferred Stock also will vote as separate classes with respect to
certain matters.
