Fig 2. Tractograms of the cortico-spinal tracts before (A) and after (B) surgery for patient 1. The color of the fiber trajectories relates to local anisotropy, with yellow indicating high anisotropy and dark red, low anisotropy. The corresponding tract positions are shown superimposed onto axial FA maps in (C) and (D), respectively. Deviation and deformation of the ipsilateral tract in the tumor proximity are apparent in the preoperative tractogram (yellow arrow).
