A summary of the intra-observer repeatability results.

All values in bold represent the mode estimate from the estimates distribution of each metric, with 95% confidence intervals displayed in parentheses. All measurements assume ADC units of 10−3 mm2/s and estimates of σεj and CoV are displayed following multiplication by a factor 100 for clarity. Whilst repeatability is excellent for mean/median gADC and log-tDV estimates, we observe a trend for poor reproducibility in higher order gADC statistics. In general, Reader 2 (R2) has worse performance than Reader 1 (R1). R1 demonstrated good reproducibility for gADC kurtosis measurements.
