a The Passing-Bablok regression scatter diagram with the regression line (solid line), the confidence interval for regression line (dashed lines), and identity line (x = y, dotted line), for mean liver dose values in Gy obtained from both methods and all 32 subjects. PETct denotes mean liver dose in Gy obtained using PET/CT imaging, and PETmri denotes mean liver dose in Gy obtained using PET/MRI imaging (n = 32, ρ = 0.97). b Blant-Altman plot for all 32 subjects, with a mean difference of 5.1 ± 5.0 Gy. The repeatability coefficient was 0.15 (12.3% of the mean)
