Fig. 3From: Linked color imaging improves visibility of reflux esophagitisReflux esophagitis (grade B) using white light imaging, linked color imaging, and blue LASER imaging. a White light imaging (WLI). Reflux esophagitis (LA grade B). b Linked color imaging (LCI). The reflux esophagitis was clearly highlighted in a purple–red color with LCI. The LCI image was scored as + 12 points representing improved visibility as evaluated by all endoscopists. c Blue LASER imaging (BLI)Back to article page
