Fig 2. Comparison of the ADC values (square millimeters per second) between the patients with vasculitis and the healthy controls for anterior WM (WM, A), central WM (B), posterior WM (C), caudate heads (D), putamina (E), thalami (F), posterior internal capsules (post IC, G), and cerebellar WM (H). There is a significant increase in the ADC values (P < .00625) for the anterior WM, central WM, thalami, and post IC in the patients with vasculitis. The horizontal lines indicate the mean ADC values in each group.
