Figure 1
A minute gastric cancer (GC, 3 mm in major diameter) identified in follow-up oesophagogastroduodenoscopy (OGD) from a patient after eradication of Helicobacter pylori (HP) infection. (A) A minute GC in white light images (WLI) (arrow) that neither the expert nor our artificial intelligence (AI) system could detect is barely discoverable in retrospective inspection. (B) Our AI method detected a minute lesion in a non-magnified view of narrow band imaging (NBI)(blue rectangular frame), confirming what the expert identified during an actual OGD procedure: GCs were recognised as light-brownish areas in surrounding green epithelium by NBI non-enlargement observation facilitated GC detection after eradication. (C) A slight lesion depression was enhanced by indigo carmine (IC) spraying, and our AI was also able to detect it (blue rectangular frame).
