From: Marginal turbid band and light blue crest, signs observed in magnifying narrow-band imaging endoscopy, are indicative of gastric intestinal metaplasia

Figure 2

Magnifying NBI endoscopic findings and representative histological findings. A Uniform round pits surrounded by a regular honeycomb subepithelial network and a regular arrangement of collecting venules are seen. No marginal turbid band (MTB) or light blue crest (LBC) is observed. B Histological view showing no atrophy or intestinal metaplasia. C Regular honeycomb subepithelial network and collecting venules subside. MTBs are seen (arrow), but LBC is shadowy. D Histological view illustrating a mild degree of intestinal metaplasia and atrophy. E Both MTBs are LBCs are distinctly visible (arrow). F Histological view showing moderate to severe mucosal atrophy and intestinal metaplasia.
