First Case in VISIUS Surgical Theatre at Florida Hospital

January 31, 2012

Intraoperative Imaging System at the Heart of New Neurosurgical Suite

WINNIPEG, Jan. 31, 2012 /PRNewswire/ – IMRIS Inc. (NASDAQ: IMRS; TSX: IM)
(“IMRIS” or the “Company”) today reported on the first neurosurgical
case that was performed in the new VISIUS Surgical Theatre at Florida
Hospital in Orlando, Fla. Dr. Melvin Field, Director of the Florida
Hospital Minimally Invasive Brain Surgery Program and Surgical Director
of the Florida Hospital Neuroscience Institute, performed the case on
December 19, 2011 involving a resection of a pituitary tumor in an
adult patient. The intraoperative MR images taken before completing the
procedure confirmed that the entire tumor had been removed as planned.
Afterwards, Dr. Field commented: “While we have been able to treat
these tumors before, the intraoperative technology allowed us to
confirm that we had fully removed the entire tumor before ending
surgery, eliminating the need for post-operative repeat imaging or
reoperation.” He continued: “We were also able to inform the patient’s
family of the surgery’s complete success before they even went in to
see him.”

“Getting it all out” is a primary patient concern when it comes to brain
tumor treatment.  According to research at the University of California
in San Francisco in 2007, improved outcomes among adult patients with
certain kinds of aggressive tumors is predicted by greater extent of
resection.  A study published by Barnes-Jewish Hospital in 2011 showed
that using intraoperative MR imaging during tumor resection, surgeons
achieved gross total resection in 93% of their patients, compared to
achieving gross total resection in only 65% of their patients when
intraoperative MR was not used.

Located within Florida Hospital Orlando’s new 35,000 square-foot neurosurgery center, the VISIUS Surgical Theatre
features two state-of-the-art operating rooms connected by a room used
for diagnostic imaging and a ceiling-mounted MR scanner that moves
between all three rooms.  The larger of the two ORs, called InnovatOR,
is a surgical center in which clinical staff and industry partners will
co-develop products, techniques and processes to improve patient
outcomes and increase clinician efficiency.  Unique to the VISIUS
Surgical Theatre is the first removable MR-compatible operating table,
which can be completely removed from the operating room to allow
surgeons to perform procedures that require a specific surgical table.

Eric Stevens, Vice President of Operations at Florida Hospital Orlando,
comments: “Our initial success is very encouraging.  The intraoperative
imaging capability of the VISIUS Surgical Theatre is central to our
strategy to improve patient outcomes in neurosurgery by combining
innovative technologies and partnering with medical industry leaders
like IMRIS.”
