Reproducibility and feasibility of optic nerve diffusion MRI techniques: single-shot echo-planar imaging (EPI), readout-segmented EPI, and reduced field-of-view diffusion-weighted imaging

Table 4 Results of quantitative evaluations of mean ADC values (10 × ⁻⁶ mm²/s)

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
