Summary

Improvement of the prognosis of gliomas around the motor strip requires that maximum tumor resection be achieved while preserving motor function. Preoperative assessment of the anatomical relationship between the tumor and the motor strip was attempted by correlation of functional and anatomical imaging. The operative field was simulated by superimposing the superficial venous image obtained by magnetic resonance (MR) using a three-dimensional phase-contrast technique on the surface anatomy scan (SAS) obtained by the multiple-slice SAS method for surface anatomical images of the brain. A MR imaging-linked whole-head magnetoencephalography (MEG) system, which consists of an array of 66 MEG sensors uniformly distributed over the whole head, was used to localize the central sulcus. Combination of these preoperative anatomical and functional images enabled us to project the best surgical management and to resect tumors around the motor strip without additional motor deficit.
