Mapping of functionally active regions for patients with mass lesions is critical for pre-surgical planning. We have developed an atlas based approach that automatically select seed points from six functional regions (motor and language regions) and computes corresponding functionally connected regions using resting state fMRI data. Functional connectivity maps were super-imposed on MR perfusion maps and structural images. Results were obtained from 22 brain tumor patients. Regions near the tumor with high correlation are seen as active regions that contribute to motor/language activities, combined with perfusion maps may help clinicians for better surgical planning.
