Fig 11. Pre- (A–C) and postoperative (D–F) axial images for patient 5: T2-weighted images (A and D), T1-weighted images (B and E), and directional color maps (C and F). Before surgery, the color images show posteromedial deviation and deformation (compression) of the posterior limb of the internal capsule (arrow, C). After surgery, the tract appears more symmetric with the contralateral tract (arrows, F) in position, cross-sectional shape, and orientation.
