ADC, apparent diffusion coefficient; rs-EPI DWI, readout-segmented echo-planar imaging diffusion-weighted imaging; rFOV, reduced field-of-view; ss-EP, single-shot echo-planar imaging; ROI, region of interest

aMean ADC values of the first scan

bMean ADC values of the second scan

cParameter value was a non-normal distribution, expressed as a median ± quartile range

dParameter value was a normal distribution, expressed as mean ± standard deviation

eχ2 value of Friedman’s test

fF value of ANOVA
