OCCC8,16 of higher-order features: conventional and parametric map extraction. Barplots of GLDM and GLRLM features are shown. The green bars illustrate the OCCC8,16 values of the conventional feature extraction. The red bars depict the OCCC8,16 values when extracted from the parametric maps. The red line at 0.85 indicates excellent agreement. The OCCCs from parametric maps show a substantial increase in stability across the 8 and 16 mm VOI diameters (Supplementary Fig. S8 contains barplots of the OCCC4–16 values of all features and Fig. S9 of the OCCC8,16 values of all features). OCCC, Overall concordance correlation coefficient; OCCC4–16, OCCC among the 4-, 8-, and 16-mm sizes of volumes of interest; OCCC8,16, OCCC between the 8- and 16-mm sizes of volumes of interest
