Note:—PNCI indicates patients with normal conventional imaging; PACI, patients with abnormal conventional imaging; FWM, frontal white matter; PWM, parietal white matter; OWM, occipital white matter; TWM, temporal white matter; PLIC, posterior limb of internal capsule. Values are means ± SD.
* For MD values (expressed in ×10⁻³ mm²/s), P_ab indicates a P value a vs b; P_bc, P value b vs c; P_ac, P value a vs c.
