Table 2.

Depiction of sciatic nerve on each map of MR was assessed by 2 radiologists in consensus according to the following scale: score 0 = poor depiction; score 1 = moderate depiction; score 2 = good depiction; score 3 = excellent depiction

	Score 0, n	Score 1, n	Score 2, n	Score 3, n	Mean score	Versus b = 0 map, P	Versus DW map, P	Versus ADC map, P	Versus FA map, P
b = 0 map	14	15	14	1	1.0 ± 0.9		<0.001	0.46	0.04
DW map	2	1	21	20	2.3 ± 0.7	<0.001		<0.001	<0.001
ADC map	10	16	16	2	1.2 ± 0.9	0.46	<0.001		0.03
FA map	20	23	1	0	0.6 ± 0.5	0.04	<0.001	0.03

A Wilcoxon sign-bank test was used to compare depiction score.
