New Milestones In Visius Surgical Theatre By Imris

- University of Virginia Striding Ahead with Intraoperative Imaging
Suite -

WINNIPEG, May 8, 2012 /PRNewswire/ – IMRIS Inc. (NASDAQ: IMRS; TSX: IM)
(“IMRIS” or the “Company”) today reported on the preliminary successes
that the University of Virginia (UVA) has achieved in their VISIUS
Surgical Theatre.   UVA clinicians have treated over 50 patients in
their VISIUS Surgical Theatre since its opening, achieving two
important milestones in the use of their new intraoperative imaging

Scott Lim, MD, Director of Pediatric & Adult Congenital Cardiac
Catheterization, performed the very first cardiac intervention in a
VISIUS Surgical Theatre when he treated a six-year old patient with a
right heart catheter diagnosis using the combination of MR and x-ray
imaging modalities of the suite.  Dr. Lim stated: “We are very pleased
with the system for cardiac procedures.  In this case, we were able to
acquire MR images in the cath lab immediately before the procedure,
which eliminated the complexities of patient scheduling and patient
movement through hospital.  In addition, by fusing MR images with
angiography, we eliminated contrast agent and reduced 99% of the
radiation we typically use on these patients.”

Jeff Elias, MD, Associate Professor of Neurological Surgery and
Neurology and Director of Stereotactic and Functional Neurosurgery, is
the first to have performed stereotactic procedures in the VISIUS
Surgical Theatre.  Using the rotational angiographic capabilities of
the bi-plane, Dr. Elias creates 3D anatomical images of the brain which
are then fused with images generated by the intraoperative MR to
enhance his visualization of the brain.  Dr. Elias commented: “The
combination of imaging modalities in this suite is critical for
procedures treating Parkinson’s or Essential Tremor.  The capability to
fuse MR and angiographic images in real time improves our ability to
plan surgery and operate with precision without transporting the

The VISIUS Surgical Theatre at UVA 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.    Mark
Shaffrey, MD, Chair, Department of Neurosurgery, who championed the
effort to implement intraoperative MR at UVA and performed the first
neurosurgical procedure in the suite, is encouraged by the initial
successes of the clinical team: “The VISIUS Surgical Theatre is
allowing us to combine biplane angiography with intraoperative MR
imaging for extremely targeted, image-guided treatment and for
visualization of anatomy to see that our surgical objectives are
achieved.  The result is simple – better surgical results for our
