Physicians can confirm if all of tumor is resected without moving

WINNIPEG, Feb. 13, 2013 /PRNewswire/ – IMRIS Inc. (NASDAQ: IMRS; TSX: IM)
(“IMRIS” or the “Company”) today announced neurosurgeons at University
of Tsukuba Hospital in Ibaraki, Japan, have performed initial tumor
removal cases using its VISIUS(®) Surgical Theatre. The intraoperative MRI system is the only one of its
kind in Japan that allows for high quality image scanning during an
operation without moving the patient.

“We hope these first cases are examples of the improved neurosurgical
outcomes we expect with our ability to scan during the procedure using
the VISIUS iMRI system,” said Prof. Akira Matsumura, M.D., one of two
neurosurgeons conducting the initial cases.

The VISIUS Surgical Theatre at University of Tsukuba Hospital provides a
unique surgical environment that enhances the surgeon’s vision at
critical times in the procedure and facilitates decision making and
precision through image guidance technology. The theatre includes both
an advanced operating room with iMRI for neurosurgery and an adjoining
room for diagnostic imaging. A high-field 1.5 Tesla MR scanner moves
on-demand on ceiling-mounted rails from the diagnostic room into the OR
to provide intraoperative images of diagnostic quality – without
introducing patient risk that would come from moving the patient -
delivering real-time information while preserving optimal surgical
access and techniques.

Using iMRI, the surgical team can assess if all of a tumor is removed
before completing the procedure. During the Tsukuba first case, which
was a low-grade glioma, an intraoperative scan found a small amount of
tumor remained that was then completely removed and confirmed with a
final scan. The second case was a transsphenoidal sella tumor and iMRI
confirmed that initial resection was complete. Studies show that
improved patient outcomes are associated with complete tumor resection.

A major teaching facility, the hospital leads Japan in providing
innovative training programs in residencies and fellowships in various
specialties. The hospital is also designated as a “Special Functioning
Hospital” that is committed to providing state-of-the-art medical care
and educational and research activities that promote patient care.

Designed to meet each hospital’s specific clinical application needs,
VISIUS Surgical Theatres can be configured to incorporate MR, CT
imaging or X-ray angiography, providing true intraoperative imaging for
open surgical applications with no patient transport.  The breadth of
open surgical applications and catheter-based treatments in IMRIS
suites creates opportunities for multiple departments to collaborate on
its investment and to optimize its utilization.


IMRIS (NASDAQ: IMRS; TSX: IM) is a global leader in providing image
guided therapy solutions through its VISIUS Surgical Theatre – a
revolutionary, multifunctional surgical environment that provides
unmatched intraoperative vision to clinicians to assist in decision
making and enhance precision in treatment. VISIUS Surgical Theatres
serve the neurosurgical, cardiovascular and cerebrovascular markets and
have been selected by leading medical institutions around the world.
