NEWPORT BEACH, Calif.--(BW HealthWire)--Dec. 1, 1997--

Operation to Be Run from InSight's Subsidiary,

Open MRI Inc., Based in Hayward, Calif.

InSight Health Services Corp. ("InSight") (NASDAQ:IHSC) today announced that its wholly-owned subsidiary Open MRI Inc. ("OMR") has been selected by General Electric Medical Systems to be a national show site for the new GE Signa Profile Open MRI system.

As a national show site, prospective Signa Profile customers will visit OMR's Hayward site, observe patient exams, discuss the Signa Profile system with radiologists and technologists and review films from a large and highly comprehensive teaching file. In addition, OMR will provide Signa Profile training for physicians and technologists as well as on-site and telephone applications support.

"The InSight show site provides a clinical environment for product enhancement in the open MRI field," said Paul Mirabella, Vice President for GE Medical Systems. "Physicians and technologists will benefit from training at a functioning site in the field and it will allow us to network with practicing radiologists to provide continuous development of Open MRI technology from a clinical perspective."

E. Larry Atkins, InSight's President and Chief Executive Officer commented, "We are honored that GE has chosen OMR to be a national show site for the GE Signa Profile. InSight and GE are working cooperatively on several initiatives and we remain committed to further expanding our relationship. Establishing strategic alliances with key vendors and suppliers will continue to play a significant role in InSight's future expansion."

Glenn P. Cato, InSight's Executive Senior Vice President and Chief Operating Officer who also serves as OMR's Chief Executive Officer stated, "The Signa Profile MRI technology delivers some of the highest quality images across a wide range of applications while providing superior patient comfort. We are committed to aggressively expanding our Open MRI presence throughout the country and the networks we develop will feature the Signa Profile systems."

Mr. Cato continued, "OMR's training programs for physicians and technologists, and its affiliation with Dr. Peter Rothschild (OMR's Medical Director) and other value added services, strengthen OMR's position as an expert in open MRI and low field imaging."

Atkins added, "Hosting a national show site for the Signa Profile system and running carefully tailored training programs at Hayward provides Open MRI Inc. with a tremendous opportunity. This program increases our role in ensuring that patients receive the optimal benefits from the GE technology, as we will be directly responsible for increasing the proficiency of diagnostic readings and development protocols. Over time, we believe this will result in increased market share for both InSight and General Electric Medical Systems."
