Abstract: Objective To study the multi-slice spiral CT (MSCT) perfusion imaging in evaluating the changes of blood supply of hepatocellular carcinoma( HCC ) before and after transcatheter hepatic arterial chemoembolization (TACE). Methods Before and after TACE, MSCT perfusion was performed in 17 patients with HCC. The perfusion indexes such as hepatic blood flow (HBF), hepatic blood volume(HBV),mean transit time (MTT),hepatic arterial fracture (HAF),permeability surface (PS), hepatic artery perfusion (HAP), portal venous perfusion (PVP) were calculated. The hemodynamic changes of HCC after TACE were evaluated according to perfusion parameters. Results After TACE, HBF,HBV and HAP found in MTT and PS before and after TACE (P > 0.05). Conclusion The parameters of MSCT perfusion imaging( HBF, HBV and HAP) can effectively evaluate the hemodynamic changes of HCC after TACE, and has important value in chnical application.
