Two representative true positive lesions. The 3D CNN correctly labeled the subcortical, ring enhancing lesion in the right occipital lobe (a) and the juxtacortical, punctual enhancing lesion in the left frontal lobe (b). FLAIR and T1C as well as zoomed views of the CE lesions without and with segmentation masks are shown. CNN, convolutional neural network; T1C, T1-weighted post-contrast; CE, contrast-enhancing
