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_(4-2) 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.
