Preoperative functional magnetic resonance imaging (fMRI) has been used to assist with the surgical management of glioma patients. This work presents initial experiences using preoperative fMRI in the treatment of 20 glioma patients. The influence of fMRI results on surgical planning has been assessed and fMRI activation maps have been validated with intraoperative mapping results via electrical stimulation. Positive outcomes of this work go towards encouraging the extended use of fMRI for neurosurgical application.
