Example segmentations of a case from the Insel32 dataset, axial view. (A) FLAIR image, plus segmentations from (B) manual raters, (C) LPA, (D) LGA, (E) nicMSlesions and (F) nnUnet (all labels) (G) DeepSCAN (just lesions) (H) nnUnet (just lesions) (I) DeepSCAN (all labels). Segmentations from LGA, LPA, and nnUnet (all labels) show erroneous segmentation of healthy-appearing tissue near the ventricles (cyan arrows). nicMSlesions labels healthy cortical grey matter as lesion tissue (cyan arrows) DeepSCAN (all labels) identified two subtle lesions (violet arrows) missed by the manual raters but subsequently confirmed by our experienced neuroradiologists.
