Fig. 5From: Linked color imaging improves visibility of reflux esophagitisRepresentative endoscopic images captured using a white light (WLI) or b linked color imaging (LCI) or c blue LASER imaging (BLI) in minimal change esophagitis (MCE); and d WLI or e LCI or f BLI in reflux esophagitis (LA grade A). Broken yellow lines delineate regions of interest (ROIs; 20 × 20 pixels). ROIs in adjacent esophageal, reflux esophagitis, and gastric mucosae were fixed in identical positions for each specific lesion in all imagesBack to article page
