Fig. 4 —Graph shows scanning delay versus mean qualitative contrast enhancement of superior mesenteric artery and vein, main portal veins, and pancreatic and liver parenchyma. Mean degree of superior mesenteric venous enhancement was significantly higher at 25-30 seconds than it was at 20 seconds (p < 0.001). Mean degree of main portal venous enhancement was significantly higher at 25-30 seconds than it was at 20 seconds (p < 0.001). Mean degree of pancreatic parenchyma was significantly higher at 15 seconds than it was at 5-10 seconds (p < 0.001) and at 20 seconds than it was 25-30 seconds (p < 0.05). Scanning delay is defined as time after bolus-tracking program detected threshold enhancement of 50 H in aorta.
