The aim of our study was to investigate the influence of neurological disorders, and the influence of tumor and perifocal edema location on functional magnetic resonance imaging (fMRI) quality. fMRI quality tended to be better the closer the tumor and the perifocal edema were located to the pmc, Hemipareses and seizures had no significant influence on fMRI quality. Therefore, hemiparetic patients do not have to be excluded beforehand. The evaluation of time courses is essential before using z-maps to localize eloquent brain regions preoperatively.
