ROC curves for the training and validation groups of the radiomics model. ROC curves for the T2WI-FS and CET1 based radiomics models for OS and CS in the training (a) and validation (b) groups. The AUC of CET1 and T2WI-FS in the training group was 0.894 (95% CI 0.817–0.970) and 0.970 (95% CI 0.940–0.999), respectively; and the AUC in the validation group was 0.821 (95% CI 0.642–1.000) and 0.899 (95% CI 0.785–1.000), respectively.
