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 ,CDE对HAE与HCC具有重要的鉴别诊断作用
Objective To explore the role of color doppler imaging (CDE) in the differential diagnosis of hepatic alveolar hydatid disease (HAE) and primary hepatocellular carcinoma (HCC). Methods After conventional two-dimensional ultrasound examination, CDE was performed to observe the blood supply status of 23 HAE lesions and 20 HCC lesions. The peripheral and internal blood flow distributions were recorded. Results No signal of blood flow was found in 2 of the HAE lesions and no blood flow was detected in the 3 HCC lesions. There was significant difference between the two groups in the distribution of internal blood flow (P <0. 001). Conclusion There is no blood supply in HAE, while the blood supply in HCC is more. As a supplement to two-dimensional gray-scale imaging, CDE has an important differential diagnosis of HAE and HCC
