Neurosurgeons say VISIUS ® is safe, more precise tool for intraoperative imaging
MINNEAPOLIS, June 26, 2013 /PRNewswire/ - IMRIS Inc. (NASDAQ: IMRS; TSX: IM) ("IMRIS" or the "Company") today reported that Le Bonheur Children's Hospital in Memphis, TN, is crediting intraoperative MRI (iMRI) within the VISIUS ® Surgical Theatre with reducing returns to the operating room for residual tumor removal by 84 percent over 2 years.
The VISIUS Surgical Theatre at Le Bonheur provides neurosurgeons with on-demand access to real-time structural brain images before, during or after a procedure without moving patients from the surgical table as the iMRI moves between rooms using ceiling rails. The multifunctional neurosurgical environment, installed in 2011, also allows for surgery in one room and diagnostic scanning in another room, in addition to intraoperative imaging.
"iMRI is an invaluable tool for me. In most pediatric brain tumors the goal is to maximally resect the entire tumor," said Paul Klimo, chief of the Division of Pediatric Neurosurgery at Le Bonheur and University of Tennessee Health Science Center. "This is a huge step in achieving this objective. For certain tumors, we have been able to improve our precision and get to them easier. We are now able to leave the OR with the knowledge of whether a tumor was completely resected or not. If not, then it is almost always because the residual tumor cannot be safely resected. Almost all of my tumor operations are done using it. I've also used it to demonstrate complete resection of arteriovenous malformation (AVM) and in tumor biopsies."In 2012, 47 percent of Le Bonheur's brain tumor surgeries were performed using VISIUS iMRI - and none of those surgeries required returns to the OR for residual tumor. In addition, the iMRI also eliminates the need, in many cases, for additional sedation that would be needed for post-operative MRI, or additional surgeries for residual tumor.
