ZOOMit DWI can provide better preoperative guidance for gastric sinus cancer with obstructive patients.

Fig. 1. CT images(a) shows that the gastric gap between the gastric antrum tumor(arrow) and the pancreatic tissue(asterisk) disappeared, indicating that the gastric cancer has invaded the pancreas. ZOOMit b=800(b) clearly shows that the contact surface of the gastric antrum tumor(arrow) and the pancreatic(asterisk) are irregular and the partial boundaries are not clear. This means that the surgical procedure was chosen for gastrojujunostomy.

Fig.2. CT images(a) shows that the gastric gap between the gastric antrum tumor(arrow) and the pancreatic head tissue(asterisk) disappeared, indicating that the gastric cancer has invaded the pancreas. ZOOMit b=800(b) shows the contact surface of the gastric antrum tumor(arrow) with the head of the pancreas(asterisk) is smooth, indicating that radical resection can be performed. Pathology(c) confirmed tumor invasion to the muscular layer, which were arranged in duct or cord.
