Abstract
Objective： To explore the difference and value of the hepatic artery –hepatic vein transit time among the hepatic diffuse diseases and focal lesions with the control group.
Methods： There are 20 cases in the study group，which including 3 fatty sparing，4 haemangiomas, 8 metastases，5 cirrhosis and 10 normal case in control group. Hepatic artery arriving time (HAAT)、Hepatic vein arriving time(HVAT)，and Hepatic artery to vein transit time(HA-HVTT) were analysed by using ACQ Time-Intensity Curve Analysis software after left median cubital vein rapid injection SonoVue.
Results： No significant difference was found in each group in HAAT. Little shorter was found in cirrhotic and metastases group in HVAT. There is significant difference of the HA-HVTT between the groups and then control group. Conclusions
The shorted of HA-HVTT have clinic value in distinguishing cirrhosis and metastases.
