To improve residual brain function following brain tumor resection we pre-operatively mapped vascular, functional and fiber tract anatomy in 11 left frontal lobe tumor patients. Reviewing the combination of MRA/DTT/fMRI images to determine the relationship between tumor and vasculature, language areas and white matter fibers, influenced the surgical approach in 10 patients. Post-operative residual function was improved compared to historical controls.
