a Bar diagrams of intra-class correlation coefficient (ICC) values of RFs robustness to different intensity rescale factors (RR and AR60) when no threshold was applied for different operators and semi-automatic algorithm. Bars in blue show the median ICC between different segmentations, applying no threshold. Range error bars (in black) encompass the lowest and highest values for different operators. b Boxplot of COVL for different intensity rescale factors (RR and AR60), applying no threshold, for the first operator (results superposable for the other operators). TLG (total lesion glycolysis) conventional parameter in our study corresponds to the TLSRE (total lesion somatostatin receptor expression)
