Merge Technologies Incorporated: Insight Health Corp. Expands Relationship With Merge eFilm

Successful
FUSION PACS implementation leads to licensing for an additional 15 Imaging
Centers.

Milwaukee, WI, October 21, 2004 – Merge Technologies Incorporated (Nasdaq:
MRGE), d.b.a. Merge eFilm, today announced the expansion of the FUSION PACS
contract by InSight Health Corp., a leading provider of diagnostic imaging
services with 118 fixed site facilities throughout the United States
serving more than 70,000 patients each month. InSight Health will expand
the use of FUSION PACS from the original contract for 10 imaging centers to
a total of 25 centers throughout the U.S. This expansion will allow
InSight Health to distribute digital diagnostic images to radiologists at
the additional centers for viewing, manipulation and interpretation, as
well as providing referring physicians with access to images and reports.

InSight Health’s positive experience with the first FUSION PACS
installations led to the expansion, according to Patricia Blank, Executive
Vice President and Chief Information Officer. “With fast access to new and
historical images and an ability to intelligently manage their
interpretation and distribution, we have accelerated the productivity of
our radiologists and technologists and have improved service to their
patients and referring physicians,” noted Ms. Blank. “Our experience with
Merge eFilm FUSION PACS software and professional services has been
outstanding. We are moving steadily forward with our deployment schedule
to further our strategic objective of achieving a filmless and paperless
workflow environment and enhancing the services we provide our referring
physicians.”

Richard Linden, Merge eFilm President and CEO, said, “The breadth and depth
of our FUSION RIS/PACS software products and professional services allows
us to meet the needs of a wide spectrum of imaging center business models,
whether individual centers owned by entrepreneurial radiologists, or large
national organizations such as InSight Health. We are pleased that a
prominent imaging center organization such as InSight Health has a level of
confidence, satisfaction and belief in a long-term relationship that led to
the expanded use of our products and services.”
