In vivo four $b$-value ${\mathrm{ADC}}_4$ ROI analysis results. (a) Pairwise wCV matrix for all implementations, shown graphically from $\mathrm{wCV}<0.1\%$ (white circles) to $\mathrm{wCV}>2\%$ (fully black circles), with groups A and B indicated. (b) Percent difference from the consensus ${\mathrm{ADC}}_4$ values for each of four datasets, for each implementation and online map. Mean difference in ADC between groups A and B was 2.8%. The 28% deviation on the PM online ADC was due to a DICOM header corruption problem.
