New system of glioma removal using intraoperative MRI combined with functional mapping

Navigation system based on intraoperative diffusion weighted imaging using open MRI

“…C. Nimsky et al reported that comparison of preoperative and intraoperative tractography depicted a marked shifting of major white matter tracts during glioma removal [19]. We developed an intraoperative imaging system [20,21] and reported the method for visualization of pyramidal tract by intraoperative diffusion weighted imaging using 0.3T open MRI and surgical navigation based on the image in the last congress [22]. The purpose of this work is to apply the proposed method to tumor removal close to pyramidal tract and evaluate the clinical utility.…”

Development of navigation system employing intraoperative diffusion weighted imaging using open MRI

“…But intraoperative visualization of nerve fibers has been hardly reported. We have developed an intelligent operating theater with 0.3 T open MRI, which has a small leakage field and suitable for intra-operative imaging [7][8][9]. It was applied to 207 cases from March 2003 to March 2004 (tumor removal rate 91%).…”

Advanced information-guided surgery by integration of data from different modality

“…In our system, information necessary for the decision making during surgery is obtained by intraoperative magnetic resonance (MR) images and updated navigation (anatomical information), functional mapping and electrophysiological monitoring (functional information) [7], and intraoperative histological examination (histological information). The surgical results of the first 46 patients with glioma were 91% of resection rate and 13% of complication rate.…”
