Linked Color Imaging and Blue Laser Imaging for Upper Gastrointestinal Screening
White light imaging (WLI) may not reveal early upper gastrointestinal cancers.Linked color imaging (LCI) produces bright images in the distant view and is performed for the same screening indications as WLI.LCI and blue laser imaging (BLI) provide excellent visibility of gastric cancers in high color contrast with respect to the surrounding tissue.
