Multislice Spiral CT Features and Its Significance of Hepatocellular Carcinoma in Interventional Therapy with Transcatheter Arterial Chemoembolization

Objective To study multislice spiral CT(MSCT) features and its significance of hepatocellular carcinoma(HCC) in interventional therapy with transcatheter arterial chemoembolization.Methods MSCT and DSA were performed in 54 cases of HCC before interventional procedure.The detection of lesions,complications and blood supply of tumors by CT and DSA were compared.The celiac artery branches were observed using the technique of VRT,MIP or MPR.Results 167 and 172 lesions,11 and 8 tumor thrombosis in portal vein,12 and 15 of hepatic arteriovenous fistula were showed by MSCT and DSA respectively.The positive rate of DSA in showing number of tumor lesions,tumor thrombosis in portal vein was slightly higher than that of MSCT,but there was no significant difference(P0.05).CTA 3D reconstruction in showing celiac artery branches was better than that with DSA , the observation of angles between celiac artery and abdominal aorta with MSCT was more convenient than that with DSA.4 cases with hepatic artery original abnormality were detected by MSCT ,they were the same as DSA.Conclusion MSCT is of important value in guidance of transcatheter arterial chemoembolization of HCC.
