摘要
Objective To evaluate characteristics of three-dimensional color power angiography （3D-CPA） imaging for hepatocellular carcinoma（HCC） and its clinicopathological significance.Methods ATL HDI-3000 ultrasonic system with C<sub>4-2</sub> superwide frequency transducer was available. 58 cases were examined and classified by 3D-CPA in order to predict the prognosis of HCC. Comparative study of 3D-CPA with pathological outcome in 30 HCC was performed, pathological characteristics including size, microvessel density （MVD）, and vascular pattern and distribution in tumor.Results Blood flows in tumor margin and branch-like intratumoral vessels were considered as the characteristics of 3D-CPA of HCC. There were more blood flow in tumor margin than in inner part as well as in large tumor than in small one. Vascular classification according to 3D-CPA visualization was related to MVD（P】0.1）. The 3D-CPA appearance for HCC corresponded to pathological findings. One-year survival rate was different in different tumor stage of HCC（P【0.05）.Conclusion 3D-CPA can reflect microvascular conditions of HCC and has clinicopathological significance in defining the TNM stage and predicting the prognosis.

There were more blood flow in tumor margin than in inner part as well as in large tumor than in small one. Vascular classification according to 3D-CPA visualization was related to MVD(P>0.1). The 3D-CPA appearance for HCC corresponded to pathological findings. One-year survival rate was different in different tumor stage of HCC(P<0.05).Conclusion 3D-CPA can reflect microvascular conditions of HCC and has clinicopathological significance in defining the TNM stage and predicting the prognosis.
