Fig. 4From: Consecutive assessment of FA and ADC values of normal lumbar nerve roots from the junction of the dura materChange in FA and ADC values from the junction of the dura mater. a FA values of all L4, L5, and S1 increased linearly up to 15 mm from the dura junction and were constant distally afterward. b ADC values of all L4, L5, and S1 nerve roots decreased linearly up to 15 mm from the dura junction and were constant distally afterwardBack to article page
