Figure 7.

The eCLE appearance of normal and pathological gastric mucosa. (A) Normal gastric mucosa in the fundus - gastric pits are round (solid arrow), net-like subepithelial capillary network patterns surround the gastric pits (dash arrow). (B) Normal gastric mucosa in the body-gastric pits are round (solid arrow). Honeycomb-like subepithelial capillary network patterns surround the gastric pits (dash arrows). (C) Normal gastric mucosa in the antrum-gastric pits are the line type (solid arrow). Coil-shaped subepithelial capillary network patterns surround the gastric pits (dash arrow). (D) Low grade gastric intraepithelial neoplasia-different sizes of gastric pits, capillary network is thickening and circuitous. (E) High grade gastric intraepithelial neoplasia-abnormal arrangement of gastric pits. The thickening capillary network and the increasing branch present a mass shape. Magnification: 1,000×.
