彩色多普勒能量图在肝泡状棘球蚴病与肝癌鉴别诊断中的应用

Application of color Doppler energy in differentiating hepatic alveolar echinococcosis from hepatocellular carcinoma

目的 探讨彩色多普勒能量显像 (CDE)在肝泡状棘球蚴病 (HAE)与原发性肝癌 (HCC)鉴别诊断中的作用。方法 常规二维超声检查后进行CDE检测 ,观察 2 3枚HAE病灶与 2 0枚HCC病灶血流供应状况 ,记录病变周边及内部血流分布特征。结果 2 1枚HAE灶内部未显示血流信号 ,而 3枚HCC灶内部亦未检出血流。两组病灶比较内部血流分布差异有显著性意义 (P <0 .0 0 1)。结论 HAE内部乏血供 ,而HCC内部为多血供。作为二维灰阶显像的补充 。

Objective To assess the role of color Doppler energy (CDE) in differentiating HAE from HCC by means of analysis of different appearence between HAE and HCC.Methods Twenty three lesions of hepatic alveolar echinococcosis(HAE) and twenty lesions of hepatocellular carcinoma(HCC) were examed by CDE examination was performed after conventional scanning with B mode ultrasound.And distributive features about blood flow inside and around the lesions of HAE and HCC were observed and recorded.Results For one aspect,no blood flow signals were detected inside 21 lesions of HAE.However,only 3 lesions of HCC had no blood flow signals inside.The probability of the difference between the two groups was less than 0.001 .For another,the flow signals around the lesions of HAE and HCC were found in 22 of HAE and 18 of HCC.The difference between them was insignificant (P> 0.05 ).Conclusions Lack of blood flow signals was displayed inside the most lesions of HAE,but plenty of signals inside those lesions of HCC, compared with HAE.It is considered that,as a supplementary means,CDE plays an important role in differentiating HAE from HCC.
