Endoscopic ultrasonography (EUS) (A) EUS showing normal layers of gastric wall, with the five-layered echo pattern being clearly visible (arrow). (B) EUS of early gastric cancer (T1a), showing a focal thickening area confined to layers 1 and 2(dotted line). (C) EUS image of advanced gastric cancer (T3); the tumor involves all layers and extends beyond the the outermost layer of the gastric wall (arrow). (D) EUS showing a metastatic lymph node (dotted line).
