Robust performance of deep learning for automatic detection and segmentation of brain metastases using three-dimensional black-blood and three-dimensional gradient echo imaging

ConclusionsThe combined 3D BB and 3D GRE DL model may improve the detection and segmentation performance of brain metastases, especially in detecting small metastases.Key Points• The combined 3D BB and 3D GRE model yielded better performance for the detection of brain metastases than the 3D GRE model (p< 0.001), with sensitivities of 93.1% and 76.8%, respectively.• The combined 3D BB and 3D GRE model showed a false-positive rate per case of 0.59 in the test set.• The combined 3D BB and 3D GRE model showed a Dice coefficient of 0.822, while the 3D GRE model showed a lower Dice coefficient of 0.756.
