Functional magnetic resonance imaging (fMRI) is a non-invasive pre-surgical tool used to map task-related brain activation in brain tumor and vascular lesion patients in order to guide neurosurgeons as they devise a surgical approach to treat these lesions and minimizes post-operative neurological deļ¬cits.

Functional Magnetic Resonance Imaging (fMRI) can be used to define brain regions which must be left intact when patients undergo surgery. Critical function is mapped with fMRI using a relevant task

These maps are generated from changes in the blood oxygen level-dependent (BOLD) signal related to neural activity

Task based functional MRI (fMRI) has been used successfully for pre-surgical localization of brain activated regions prior to the performance of brain surgery

To date, usage of fMRI in pre-surgical planning has played a valuable role for neurosurgical procedures

In our pre-surgical Analysis group, for each patient we use various types of language, Memory and Motor Tasks, based on individual medical conditions (tumor region) and neurosurgeons request to help the neuro-surgical team evaluate specific function.

All tasks followed a block design paradigm and Patients are instructed to perform tasks before scanning.

FMRI data is analyzed using FEAT (FMRI Expert Analysis Tool), part of FSL (FMRIB’s Software Library,
