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.
