Interobserver agreement of cortex, medullary and tumor T2 values. Interobserver agreement of the cortex, medullary and tumour T2 values. Bland-Altman plots illustrate the interobserver variability for native cRCC, medullary and cortex T2 values. Specifically, the mean differences were 1.95 (95% confidence interval (CI): − 8.61 – 12.52) for the cRCC tumor area with a CoV of 2.76, − 2.26 (95% CI: − 12.45– 7.94) for the renal cortex with a CoV of − 2.3 and − 1.03 (95% CI: − 13.67 – 11.61) for the medullary pyramids with a CoV of − 6.26. The mean difference of the data is illustrated by the central horizontal line. The upper and lower reference lines indicate the upper and lower limits of agreement. The confidence intervals for the mean and limits of agreement are indicated by the dotted lines. CoV: Coefficient of variation
