Fig. 3From: AI-based detection of contrast-enhancing MRI lesions in patients with multiple sclerosisTwo representative false negative lesions. Relatively small, low-contrast lesions (a) and predominantly lesions with infratentorial location (b) were missed by the 3D CNN. FLAIR and T1C as well as zoomed views of the CE lesions with annotation of the respective lesion are shown. CNN, convolutional neural network; T1C, T1-weighted post-contrast; CE, contrast-enhancingBack to article page
