Quantitative comparison of functional MRI and electro-cortical stimulation for function mapping

Abstract

Mappinlg functional areas of the brain is of vital importance for plallnning tumor resectiol. A accurate mapping provides information to leurosurgeons about which areas of the brain are eloquent, and should be avoided while removinlg the tumor. With the recent increase in the use of functional MRI for such pre-surgical planning, there is a nleed to validate that fMRI activation mrapping is consistent with the map)ppillg obtainled durinlg surgery with the standard technique, direct electro-cortical stimulationl. To this end, this thesis quanltitatively comlpares functionlal MRI lnapping with electro-cortical stimulation mapping.
