Preoperative Evaluation with fMRI of Patients with Intracranial Gliomas

摘要: Introduction. Aggressive surgical resection constitutes the optimal treatment for intracranial gliomas. However, proximity of a tumor to eloquent areas requires exact knowledge its anatomic relationships functional cortex. The purpose our study was evaluate fMRI’s accuracy by comparing it intraoperative cortical stimulation (DCS) mapping. Material and Methods. Eighty-seven patients, with presumed glioma diagnosis, underwent preoperative fMRI DCS mapping during resection. Findings were considered concordant if identified centers less than 5 mm apart. Pre postoperative Karnofsky Performance Scale Spitzer scores recorded. A MRI obtained assessing extent Results. interest in all participants. concordance between 91.9% regarding sensory-motor cortex, 100% visual 85.4% language. Data analysis showed that patients better condition demonstrated higher rates, while there also weak association grade rate. mean 96.7%. Conclusions. Functional is highly accurate methodology language mapping, remains necessary localization.
