[Fusion imaging of three-dimensional angiographies of arteries and veins around the stomach by multiphase fusion technique under single breath-hold using 16-detector multislice CT].

: Postcontrast CT scan using multislice CT was performed in 10 patients prior to laparoscopic gastric cancer surgery. Using 16-detector multislice CT, images were obtained at both arterial and venous phases under a single breath-hold. Three-dimensional CT angiography at arterial and venous phases was respectively reconstructed using the volume-rendering technique and then fused. Multiphase fusion imaging was able to demonstrate clearly, simultaneously, and three-dimensionally the gastric arteries and veins without a respiratory gap. In conclusion, multiphase fusion images were considered to be very useful for the intraoperative navigation of laparoscopic gastric cancer surgery.
