Fig 1. A, Change in mean fractional anisotropy in patients with 0 or 1 vascular risk factor (n = 10). *1 indicates significant reduction from baseline (P < .05); *2 indicates significant improvement from baseline (P < .05). B, Reduction of mean fractional anisotropy in patients with more than 1 vascular risk factor (n = 6). *1 indicates significant reduction from baseline (P < .05); *2 indicates further significant reduction from the end of RT (P < .05).
