Research on the application of CT enhancing scan based on bolus tracking technique in upper abdomen / 中国医学装备

ABSTRACT

Objective: To evaluate the application value of CT enhancing scan based on bolus tracking technology in the upper abdomen. Methods:200 patients were examined by CT in the upper abdomen. Contrast agent was injected through the hand vein at 1.5 ml/kg, with pressure of 300 Pa, flow rate 2.5 ml/s. Before injection, we must complete the first scanning .Then , another 2 or 3 scans were done. Results:188 cases can show abdominal aorta, hepatic artery, splenic artery, hilar vessel branches, portal vein, inferior vena cava very well. Another two cases failed .The others were not ideal because of portal hypertension. Conclusion:CT enhancing scan based on bolus tracking technique in the upper abdomen can obtain good images to meet clinical needs.
