MGMT and astrocytoma (excluding glioblastoma): Previous studies have constructed a radiomics model with 6 fully correlated features from 6 sub-regions and 4 image modalities, with an AUC of 0.88 and an accuracy of 80%36。Wei et al.37 combined the radiomics features of the tumor and peritumoral edema area on the three imaging sequences to predict the MGMT status of grade II-IV astrocytoma, and the model fused with radiomics features achieved the best performance.
