All the 7 cases underwent plain and Double-phase dynamic CT enhancement scan. Results Among 5 cases of gastric, 4 cases were located in Gastric body and 1 case was located in gastric antrum, among this 4 cases were located in the lesser curvature. Among 2 cases of duodenal, one was located in descending part of duodenum and the other was located in the third portion of duodenum, Masses long axis of Seven lesions were between 1.5 and 13.2cm. The average CT values of the non-contrast CT scan and double phases dynamic CT scan were 35HU, 77 HU, and 91 HU respectively.
