[Three-dimensional angiography of arteries and veins around the stomach using multislice CT for preoperative simulation of laparoscopic gastric cancer surgery: trial of multiphase fusion method].

Postcontrast CT scanning using multislice CT was performed for 20 patients with gastric cancer. Three-dimensional (3D) CT angiography of the arterial and venous phases was reconstructed using the volume-rendering technique and then fused. 3D-CT angiography showed the arteries and veins around the stomach, and multiphase fusion imaging was able to demonstrate clearly and three-dimensionally the gastric vascular anatomy. In conclusion, the multiphase fusion image was considered to be useful in the preoperative simulation of laparoscopic gastric cancer surgery.
