Region	Segment	ADC	D slow	D fast	f slow/fast
1	5/8	0.798	0.929	0.022*	0.761
2	6/7	0.895	0.708	0.086	0.005*

5	5	0.230	0.735	0.167	0.663

P values (Shapiro–Wilk tests) indicate deviations from normal distribution (P < 0.05). Measurements of D _fast and f fractions were non-normally distributed, D _slow values were normally distributed
