Workflow of the radiomic analysis in this study. Abs. = absolute, AUC = area under the ROC curve, CE-T1W = contrast-enhanced T1-weighted, GLCM = gray level co-occurrence matrix, ICC = intraclass correlation coefficient for absolute agreement, PCC = Pearson correlation coefficient, PFS = progression-free survival, ROC = receiver operating characteristic curve, SHAP = Shapley additive explanations, wavelet-LL = low-low band wavelet transforms.
