Fig. 3

Boxplots of features extracted conventionally and from parametric maps. Exemplary boxplots of the first-order feature maximum and the higher-order feature GLSZM small area emphasis across the different volume-of-interest (VOI) sizes. The left column shows boxplots of the conventional feature extraction with a wide variety of results across the VOI sizes, affecting the median. The same features are shown on the right, but values were retrieved from the parametric maps. Please also note the range on the y-axis. Boxplots for all features are provided in the Supplementary material (Fig. S6 contains boxplots of conventionally extracted features and Fig. S7 of extraction from parametric maps)
