Brief Summary

Many clinical studies have been reported on iMRI, however, their evidence levels are relatively not as good as what people hope they will be. Based on the available literature, there is, at best, level 2 evidence that iMRI-guided surgery is more effective than conventional neuronavigation-guided surgery.

The investigators aim to do a single center prospective randomized triple-blind controlled clinical trial to assess the effect of 3.0T high-field intraoperative MRI-guided glioma resection on surgical efficiency and progression-free survival of malignant glioma to provide a level 2A evidence for its clinical application.

Detailed Description

Since the first introduction of the GE Signa System by the Brigham and Women's Hospital as the world's first intraoperative MRI in 1993, iMRI has been so increasingly applied that it has been one of the most important techniques and concepts in the field of neurosurgery. Many clinical studies have been reported on this respect, however, their evidence levels are relatively not as good as what people hope they will be.Based on the available literature, there is, at best, level 2B evidence that iMRI-guided surgery is more effective than conventional neuronavigation-guided surgery.

Rationale: Intraoperative magnetic resonance imaging (MRI)-guided intracranial surgery, one of whose most frequently reported indications is cerebral glioma surgery, may help update images for navigational systems, providing data on the extent of resection and localization of tumor remnants, and thereby enable intraoperative reliable immediate resection control to eliminate the effect of brain shift on the extent of resection. Intraoperative MRI systems can be divided into low-field intraoperative MRI(0.5T or less) and high-field intraoperative MRI (1.5T or more) according to their various field strengths. The latter enables intraoperative imaging at higher quality and more available imaging modalities but with more cost and equipment requirements.

Purpose: We aim to do a single center prospective randomized triple-blind controlled clinical trial to assess the effect of 3.0T high-field intraoperative MRI-guided glioma resection on surgical efficiency and progression-free survival of malignant glioma. We hypothesize that the use of high-field intraoperative MRI will enable more complete tumor resection than conventional neuronavigation-guided resection,reducing the morbidity and leading to more improved progression-free survival and quality of life in patients with malignant glioma.

2. Parietal lobe, which divided into inferior parietal lobule (BA40-supramarginal gyrus, BA39-angular gyrus), parietal operculum (BA43), and primary somatosensory cortex (BA1, BA2, BA3)

3. Temporal lobe, which divided into transverse temporal gyrus (BA41, BA42), superior temporal gyrus (BA38, BA22/Wernicke's area), middle temporal gyrus (BA21)

4. Insular lobe.
