Autofluorescence imaging and magnification endoscopy

Figure 3 Early gastric adenocarcinoma at the level of the gastric angle. A: Irregular ulcer visualized in white light endoscopy (WLE); B: Autofluorescence imaging showing in magenta the neoplastic margins and a larger lesion extension, as compared with WLE; C: Magnifying endoscopy with narrow band imaging showing a modified pit pattern, with irregular and distorted vascular pattern in the center suggesting high-grade dysplasia/ early cancer, and with villous pits and light blue crest sign in the margins suggesting intestinal metaplasia.
