Note:—Missed indicates missed brain metastases in the test cohort; FPs/scan, false-positive lesion findings per patient; Dice coefficient, similarity score reported as median; Majority Voting Scheme, fusion of the 5 deep learning models from the 5-fold cross-validation; First Fold, first deep learning model from the 5-fold cross-validation.
