Abstract Objective To compare the effects of the different contrast media concentration on the visualization of pancreatic arteries using 64-Detector Spiral CT.Methods 120 cases who underwent abdominal enhancement CT scanning were randomly divided into group A (n = 60) and B (n = 60). The contrast media concentration was 300 mgI/ml for group A and 370 mgI/ml for group B respectively, both groups shared the same contrast media dose algorithm and injection speed, with 0.5 gI/kg body weight and 4 ml/s respectively. Reformating the pancreatic arteries via MIP (maximum intensity projection), VR (volume rendering) and MPR (multi-planar reconstruction).Results The CT value of the abdominal aortic celiac opening of group B is significantly higher than A (P < 0.01). The visualization scores of pancreatic arteriesin Group B are significantly higher than A (P < 0.05). The visualization ratios of pancreatic arteriesin Group Bare higher than A, the differences of AIPDA、PIPDA、DPA、TPA、PMA、CPA between the 2 Groups have statistically significant (P < 0.05).Conclusion Pancreatic arteries could have a better visualization by using 370 mgI/ml contrast media in pancreatic artery scanning.
