Figure 4:

Distribution of intensity and texture intraclass correlation coefficient (ICC) values under different conditions. ICC for, A, B, intensity and, C, D, texture features extracted from T2-weighted fluid-attenuated inversion recovery (T2W FLAIR) (left) and T1-weighted (T1W) postcontrast (right) using either z score normalization (z-score) or histogram matching (hist-m.) compared with features extracted from not-normalized (no norm) images. Significant differences in the feature group mean ICC between feature extraction strategies (paired Wilcoxon test) are indicated with brackets.
