Voxel-based analysis results overlaid on selected axial slices from the mean FA template derived using 40 healthy controls (CON) and 60 patients with MTBI scanned within a few days of injury. The top and bottom rows depict voxel clusters where the mean FA and MD of patients were significantly greater and less than controls, respectively, at P < 0.05 corrected for age, sex, education, and multiple comparisons.
