Figure 1:
Distribution of intraclass correlation coefficient (ICC) values per feature group under default feature extraction settings. Each boxplot represents the distribution of one radiomics feature group (shape, intensity, texture) between scan and rescan for the cohort of 48 patients. A, T2-weighted fluid-attenuated inversion recovery (T2W-FLAIR). B, T1-weighted (T1W) postcontrast. Features were extracted from nonnormalized images using the PyRadiomics default settings (no normalization, constant bin width for intensity quantization).
