Although they concluded that the radiomics signature of T2 FLAIR achieved an AUC of 0.871, an accuracy of 0.845, a sensitivity of 0.901, and a specificity of 0.891 for discriminating EGFR mutation status using an independent testing data set, they also assumed that EGFR expression was consistent between the metastatic tumor and the primary tumor, which may not be accurate as discussed above. The gene discussed is EGFR; the disease is metastatic neoplasm.
