Detection of damaged regions of the CWM by use of voxel-based analysis with DTI. When FA values in all voxels on the FA map were compared voxel by voxel between 2 patient groups (patients with and without chronic neuropsychiatric symptoms), voxels showing a significant difference in FA (P < .03) between groups were identified as reddish voxels on the FA template. The number of reddish voxels was greater in the region corresponding to the deep CWM, including the centrum semiovale, than in other regions.
