Latest joint application of these two technologies provides direct, intraoperative visualization during surgery to treat a childhood brain tumor
MINNEAPOLIS, MN and IRVINE, CA /CNW/ - IMRIS Inc. (NASDAQ: IMRS) (TSX: IM) ("IMRIS") and MRI Interventions, Inc. (OTCQB: MRIC) today announced that a surgical team at Cook Children's in Fort Worth, Texas, has performed the first pediatric laser ablation procedure in an IMRIS VISIUS® Surgical Theatre combining the use of MRI Interventions' ClearPoint® Neuro Intervention System as the navigation platform and VISIUS intraoperative MRI (iMRI). The combination of these two medical technologies provided continuous real-time visualization and guidance throughout a neurosurgical intervention to treat a brain tumor.
"This initial operation went very well," said Dr. John Honeycutt, Medical Director of the Cook Children's Department of Neurosurgery, who led the operation. "Access to real-time intraoperative imaging and guidance with VISIUS and ClearPoint technologies together allowed accurate placement of the laser catheter for thermal ablation of the tumor. Since this tumor was small, deep, and next to critical structures, having ClearPoint to assure accuracy was critical to successful ablation of the tumor with no side effects or complications. The VISIUS iMRI allows us to do the complete procedure in a proper operating room."
The ClearPoint navigation platform is the only technology that enables minimally-invasive neurosurgery under continuous MR guidance, offering surgeons real-time direction and a direct view of the inside of a patient's brain during a procedure. MR provides superior visualization of the brain's tissue compared to other imaging technologies.
The VISIUS Surgical Theatre allows use of MR in the operating room and over the OR table. For neurosurgery, VISIUS iMRI at Cook Children's brings high-field MR to the patient inside the operating room on ceiling-mounted rails. The fully integrated suite allows the scanner to move between an operating room and a diagnostic room, providing on-demand access to high resolution MR images - before, during and after procedures without moving the patient.
Using the ClearPoint system with VISIUS iMRI, Dr. Honeycutt was able to see and select the tumor in the brain, establish a safe trajectory, and visualize the laser probe on MR images as it was inserted to the target location. He was then able to utilize real-time MR thermometry to monitor progress as the laser probe heated the target area to the desired temperature for therapeutic destruction of the tumor tissue, preserving surrounding healthy tissue in the process. MR is the only imaging technology that will safely allow this continuous soft tissue visualization during surgery. Finally, Dr. Honeycutt was able to confirm results of the procedure using the iMRI before the patient was moved from the operating table.
