摘要
目的 :探讨彩色多普勒血流显像 ( CDFI)和彩色多普勒能量图 ( CDPI)在肝脏肿瘤中的应用。方法 :对 2 4 1个肝脏肿瘤进行了彩色和能量多普勒及脉冲多普勒检查。结果 :原发性肝细胞癌 ( HCC) ( 5 6例 6 9个肿块 )和肝血管瘤 ( 6 7例 89个肿块 )的血流信号检出率有显著性差异 ( 97.1 % ,4 4.9% )。HCC中 94 .2 %显示肿块周边弧形彩色血流包绕征 ,82 .6 %显示肿瘤内部片状或条索状彩色血流及肝内动脉扩张 ,流速加快 ,而肝血管瘤无以上特点。结论 :彩色和能量多普勒血流显像对肝脏肿瘤良恶性的鉴别有重要价值。
Objective:To evaluate the application of CDFI and CDPI to diagnosis of hepatic tumors.Methods:Two hundred and forty one hepatic tumors were investigated by color and power Doppler flow imaging.Results:There was a significant difference in the detectable rates of blood flow signals between primary hepatocellular carcinoma (HCC)(69 tumors in 56 cases)and hepatic hemangioma (89 tumors in 67 cases),97 1%(67/69) and 44 9% (40/89) respectively.Among the 69 tumors of primary hepatic carcinoma,abnormal color blood flow around tumor nodules was observed in 65 tumors (94 3%), and blood flow within 57 (82 6%) tumors was seen.These characteristics were found in most of the primary hepatic carcinoma but not in hepatic hemangioma.Conclusion:Color and power Doppler flow imaging is useful in the differential diagnosis of hepatic tumors.
