a–c Correlation plots of measurements using 4b (b = 0, 100, 200, 300 s/mm²) plotted against a 3b2 (b = 0, 200, 300 s/mm²), b 3b1 (b = 0,100, 200 s/mm²), and c 2b (b = 0, 300 s/mm²). r_s = spearman’s rank correlation coefficient. d–f Bland-Altman-Plots showing the differences between ADC measurements plotted against their corresponding average with 95% limits of agreement (dotted lines)
