TOSHIBA PARTNER AWARDED FIRST PLACE FOR CARDIAC IMAGING RESEARCH AT ISMRM

Research Validates Use of Non-Contrast Imaging Techniques for Diagnosing Disease

TOKYO, August 23, 2006 — Toshiba Medical Systems Corporation (TMSC) today announced that Dr. Katsumi Nakamura of Tobata Kyoritsu Hospital in Japan received first place honors for his research in the area of non-contrast magnetic resonance angiography (MRA) imaging. Nakamura, a radiologist and long-time Toshiba collaborator, received accolades for his poster presentation comparing non-contrast fresh blood imaging (FBI) to 16-slice computed tomography (CT) for the diagnosis of peripheral vascular disease using Toshiba’s 1.5T MRI system. The poster was presented at the 14th annual International Society for Magnetic Resonance in Medicine (ISMRM) Scientific Meeting & Exhibition, held May 6-12, 2006 in Seattle, Wash.

“Toshiba and its partners have pioneered research into the use of contrast-free MRA for the diagnosis of peripheral vascular disease,” said Bob Giegerich, director, MR Business Unit for Toshiba. “ISMRM’s recognition of Dr. Nakamura’s research further highlights FBI as an effective technique within the scientific community, and strengthens the use of MR technology in this area of medicine.”
