Clinical applicability of gastroscopy with narrow-band imaging for the diagnosis of Helicobacter pylori gastritis, precancerous gastric lesion, and neoplasia

Figure 7 Magnifying narrow-band imaging endoscopic findings of early gastric cancers. A: Conventional white-light endoscopy shows a slightly elevated and depressed lesion at the gastric corpus; B: Magnifying narrow-band imaging (NBI) endoscopy demonstrates an irregular microvascular and microsurface pattern with a demarcation line (yellow arrows); C: Conventional white-light endoscopy shows a reddish depressed lesion at the gastric antrum; D: By magnifying NBI endoscopy, an irregular microsurface pattern is identified within the demarcation line (yellow arrows).
