Figure 4 Magnifying narrow-band imaging findings of microvascular patterns for diagnosing the gastric polypoid lesions. A: Honeycomb-like pattern (fundic gland polyp); B: Dense vascular pattern (hyperplastic polyp); C: Fine network within a light brown area (low grade dysplasia); D: Core vascular pattern (low grade dysplasia).
