From: Linked color imaging improves visibility of reflux esophagitis
Reflux esophagitis (grade C) using white light imaging, linked color imaging, and blue LASER imaging. a White light imaging (WLI). Reflux esophagitis (LA grade C). b Linked color imaging (LCI). The reflux esophagitis (LA–C) was highlighted in a purple–red color with LCI. The LCI image was scored as + 13 points representing improved visibility as evaluated by all endoscopists. c Blue LASER imaging (BLI)
