Bland–Altman plots with 95% CI comparing the measurements of the two observers to estimate the interobserver reproducibility for Pre-TBF (a), Post-TBF (b), and ΔTBF (c). The mean differences between the first and the second measurements (y-axis) plotted against their averages (x-axis). The horizontal lines (blue solid line) are drawn at the mean difference of the two times measurements and the limits of agreement (red dotted lines). The ASL parameter measurements by the two observers showed good agreement
