Comparison of CT perfusion imaging and hepatic reserve function of normal liver

Objective To assess the precise value of CT perfusion imaging in normal liver.Methods CT perfusion imaging and hepatic reserve function of normal liver were performed in 20 volunteers without any liver disease.Results The hepatic arterial perfusion(HAP) = 0.18±0.08 ml/min·ml,portal vein perfusion(HPP) = 0.98±0.33 ml/min·ml,total liver perfusion(TLP) = 1.1±0.12 ml/min·ml,HAI = 19.2%,PVI = 80.8%,and ICGR15 = 1.8%.Conclusion CT perfusion imaging can well reflect the hemodynamic changes in the liver,and can be regarded as an important imaging indexes to evaluate the hepatic reserve function.
