Clinic Application with MSCT Perfusion in Liver Tumor

Objective To study the changes of MSCT perfusion parameters of benign or malignancy tumor in liver and discuss differentiate diagnosis.Materials and Methods CT perfusion of the liver were obtained in 100 individuals who include 15 patients with benign tumor and 81 patients with malignancy tumor and 4 as control subjects. Liver perfusion parameters included blood flow (BF), blood volume (BV), mean transit time (MTT), permeability surface (PS) ,Hepatic Perfusion index (HPI) and Hepatic Arterial Perfusion(HAP)were calculated to evaluate the dynamic features of liver tumors.Results Compared with benign tumor of liver and control group, HPI,BF and HAP in malignancy tumor group were increased significantly, and MTT was decreased significantly. BV and PS had no difference between liver tumors and control group.Conclusion Hepatic perfusion parameters (HPI,BF, HAP and MTT) measured with CT can be used to evaluate the dynamic features in liver tumors, which have importance clinic value in differentiate diagnosis of benign or malignancy tumor.
