Improvement of the prognosis for patients with glioma requires the achievement of greater extent of resection and less residual tumor. Extended surgical resection of glioma with preservation of essential brain function may be possible using multimodal imaging techniques for anatomy and function. Integration of magnetic resonance (MR) angiography and surface anatomical MR imaging can provide preoperative views of the sulci, gyri, cortical veins and lesions in the operative field. Diffusion-weighted MR imaging can show the position and orientation of subcortical fibers including the pyramidal tract for reference in deep subcortical resection. Functional MR imaging provides extended and multiple activation images of the motor and other eloquent cortices. Magnetoen-cephalography can localize somatosensory, auditory and visual functions with pinpoint accuracy in time and space. Intraoperative cortical stimulation can also localize language, motor and sensory cortices. Neuronavigation systems are useful to project all the functional and anatomical information into the surgical field. We emphasize the complimentary usefulness and combination utility of these methods.
