摘    要:目的: 探讨彩色多普勒超声 (CDFI) 在原发性肝癌 (HCC)、转移性肝癌 (HLC) 及肝血管瘤(HHA) 鉴别诊断中的临床应用价值。方法: 通过100 例肝肿瘤患者及40 例正常对照组 (NS) CDFI参数对比分析,比较HCC、M LC 和HHA 各组间CDFI影像学差异及特点。结果: (1) HCC 组与其他各组比较肿瘤内部及周边部动脉血供明显丰富 (P< 0.005), 肝动脉直径明显增粗, 收缩期最大流速和舒张期最小流速明显增快 (P< 0.01); (2)M LC 组与HHA 组比较肿瘤周边动脉血流检出率显著增高(P< 0.005), 内部血供无明显差异, 肝动脉直径及血流速度与NS组比较三组之间无明显差异 (P> 0.05); (3) 阻力指数 (RI) 四组之间无显著差异 (P> 0.05)。结论: CDFI在肝脏肿瘤鉴别诊断中有重要的临床应用价值。

Abstract:Objective:Evaluation of color Doppler flow imaging(CDFI)in the differentiation of hepatic cellular carcinoma(HCC),metastatic liver cancer(MLC)and hepatic hemangioma(HHA).Methods:We used CDFI to examine 60 HCCs,20 MLCs,20 HHAs and 40 controls to compare the differentiation indices in this 4 groups.Results:(1)HCC demonstrated richer intratumoral and peritumoral blood flow( P <0 005).The hepatic artery diameter was significantly widened.The systolic and diastolic velocity were obviously higher compared with other groups ( P <0 01,respectively).(2)MLC showed a higher blood flow around than HHA.No significant difference in diameter and velocity of the hepatic artery between MLC,HHA and control was found( P >0 05).(3)Resistant index(RI)had no significant difference between the 4 groups( P >0 05).Conclusion:CDFI plays a key role in differentiation of HCC,MLC and HHA.
Keywords:Color Doppler flow imaging  Hepatic cellular carcinoma  Metastatic liver cancer  Hepatic hemangioma
