Reproducibility and accuracy of ADC values assessment. Bland–Altman plots show reproducibility of mean ADC values in the optic nerve during repeat exams. rs-EPI DWI, readout-segmented echo-planar imaging diffusion-weighted imaging; rFOV, reduced field-of-view; ss-EPI, single-shot echo-planar imaging. a1–a3 Reproducibility evaluation of mean ADC values of rs-EPI DWI. a1–a3 are the Bland–Altman plots of ROI1, ROI2, and ROI3, respectively. b1–b3 Reproducibility evaluation of mean ADC values of rFOV DWI. b1–b3 are the Bland–Altman plots of ROI1, ROI2, and ROI3, respectively. c1–c3 Reproducibility evaluation of mean ADC values of ss-EPI DWI. c1–c3 are the Bland–Altman plots of ROI1, ROI2, and ROI3, respectively. In each plot, the solid line represents the average value (percentage) of the difference between the two scans; the dashed lines represent the 95% CI (confidence intervals) of the difference; the blue error bars close to the y-axis represent 95% CI of upper limit, 95% CI of arithmetic mean, 95% CI of the lower limit, respectively
