Erratum: MRI-based deep-learning method for determining glioma MGMT promoter methylation status (JNR Am J Neuroradiol (2021) 42 (845–852) DOI: 10.3174/ajnr.A7029)

There was an error in the Python code for the 3-fold cross-validation procedure. This resulted in the use of the training cases instead of the set-aside test cases for the testing procedure for molecular marker accuracy. This caused our reported accuracies from the TCIA/TCGA data set to be artificially inflated. The corrected accuracies for the Table (computed using nnU-Net1), along with the updated receiver operating characteristic (ROC) curve for Fig 3 are provided here. The updated accuracies do not outperform other reported methods for MGMT molecular marker prediction using MR imaging.
