肝癌的能量多普勒和三维彩色血管能量成像研究

目的 探讨肝癌的血供特点及能量多普勒（CPA）和三维彩色血管能量成像（3D-CPA）对肝癌的诊断价值。方法 采用ATLHDI-3000超声仪，C4-2超宽频探头，对53例原发性肝癌（HCC）和44例肝转移癌（HM）进行CPA检查，其中57例3D-CPA检查与X线动脉造影（AG）对比，32例与病理学检查结果对照。结果 HCC与HM均以瘤外弧形血流及瘤内树枝状分支血流为特点。3D-CPA检查66.67%的肝癌病例表现为特征性的“众星捧月征”，此结果与AG及病理检查结果相一致。结论 3D-CPA目前可人微言轻评价肝癌血供的首选方法。

Study on hepatic carcinoma with color power angiography and three-dimensional color power angiography

Objective　To evaluate the characteristics of blood supply in hepatic carcionoma and diagnostic value of color power angiography (CPA) and three-dimensional color power angiography (3D-CPA) in hepatic carcinoma.Methods　CPA examination was preformed by ATL HDI-3000 ultrasonic system and C4-2 superwide frenquency transducer in 53 hepatocellular carcionomas (HCC) and 44 hepatic metastases (HM). Comparative study was done between 3D-CPA and X-ray angiography (AG) in 57 cases or pathology examination in 32 cases.Results　The blood supplies of HCC and HM were characterized by radial blood flow signals in surrounding regions and by tree branch blood flow signals in intratumor with CPA,and by signals as “a myriad of stars surrounding the moon” in 66.67% of hepatic carcionoma with 3D-CPA. The results were corresponded to the result of AG and pathology examination.Conclusions　3D-CPA can be used as the best method to evaluate the blood supply of hepatic tumors.
