Illustrations of polyps missed by reporting radiologists during initial reading in the original trial in 2D views (upper images) and 3D endoluminal views (lower images), which were detected by our MTANN CAD scheme. (a) A small polyp (6 mm; hyperplastic) in the sigmoid colon was detected correctly by our CAD scheme (indicated by an arrow). This polyp was missed in both CTC and reference-standard optical colonoscopy in the original trial. (b) A small polyp (6 mm; adenoma) in the sigmoid colon. (c) A sessile polyp on a fold (10 mm; adenoma) in the ascending colon.
