Fig. 2

Extraction of feature quantity from parametric maps. Slices of the parametric maps of the first-order feature skewness are shown. We copied volumes of interest (VOIs) with 4 (a), 8 (b), and 16 (c) mm diameter from the conventional feature extraction onto the maps. Feature quantities, visualised by the map, were extracted with PyRadiomics using the mean value of the VOIs
