Results: In 6 patients the relationship of Broccas area and precentral motor area to the frontal lobe tumor was identified allowing pre-operative neurosurgical planning to minimize language and motor disruption. Diffusion tensor images were corrupted by motion in one patient but successfully demonstrate the impact of tumor on white matter tracts in 5 patients. Fractional anisotropy images, showed disruption of the left arcuate fasciculus in one patient, deviation/deformation in 2 cases and unaffected by tumor in the remaining two cases.
