Bland Altman plots (A–E) for SNR and CNR for measurements with RT and diagnostic setup. Graphs show difference between two measurements plotted against their average. Solid lines indicate the mean of differences and the limits of agreement (mean ± 1.96 × SD). Corresponding confidence intervals are shown as gray-shaded areas. A–C: SNR in anatomical ROIs for T2w and distortion-corrected DW-MRI with b-values of 150 and 800 s/mm2, respectively. D, E: SNR in lesion and CNR in lesion vs. adjacent tissue for T2w MRI, respectively. F: Boxplot for the relative difference of SNR and CNR between both scan setups for A–E, accordingly.
