Preoperative functional MRI as noninvasive method of mapping of the brain cortex at gliomas which amaze functionally significant zones

Abstract

Results of tool inspection of 36 patients with glial tumours of a different degree of malignancy which were localized nearby or directly in sensorimotor area of a cortex of a brain, by means of techniques MRI, MR-venography and functional MRI are analysed. Use of the given techniques has allowed to spend mapping cortex of hemispheres of a brain with visualization of local areas of activation and their extrapolation on corresponding anatomic structures of a brain, has enabled to determine a degree of risk of occurrence of neurologic deficiency already on preoperation a stage, promoted optimization of medical tactics and minimization of undesirable consequences of surgical intervention, increase of safety.
