Summary

Light Blue Crest (LBC)
  1. 1.

    Phenomenon that can only be visualized using NBI

     
  2. 2.

    Fine light blue (light cyan colored) linear reflections located on the epithelial margins, visualized using M-NBI

     
  3. 3.

    Indicator of the brush border of intestinal metaplasia

     
White Opaque Substance (WOS)
  1. 1.

    Phenomenon that can be visualized using both WLI and NBI

     
  2. 2.

    White opaque substance visualized by reflections/strong scattering of whole projected lights located in the surface epithelium of the IP.

     
  3. 3.

    Nature is still unknown
