Fig 3. The graphs present the measured mean FA values in the nonisotropic voxel (2 x 2 x 6 mm³) and in the isotropic voxel (2 x 2 x 2 mm³).

A, Statistically significant FA differences were noted at the centrum semiovale (P < .0001), SLF (P < .0001), thalamus (P < .0001), and red nucleus (P < .0001).

B, The areas without statistically significant differences.
