彩色多普勒血流显像在原发性和继发性肝脏肿瘤的作用

目的：探讨彩色多普勒血流显像(CDFT)在肝脏肿瘤的应用，为诊断和鉴别诊断提供依据。方法：采用ALT3000彩色多普勒超声显像仪对原发性肝癌(HCC)(27例)和转移性肝癌(MHC)(21例)肝脏实性占位病变进行检查。所用指标为最大血流速度(Vmax)；阻力指数(RI)；最大与最小血流速度之比(M/B)和血流量(FV)。结果：HCC组和MHC组肝脏实性占位病变的瘤内血流信号检出率(77．1％，37．5％)有明显差别。HCC血流抵达瘤体中心区域，而MHC的血流多位于肿块的外侧。结论：HCC与MHC的血流动力学表现明显不同，CDFI对二者的诊断及鉴别诊断有重要作用。

The Application of Color Doppler Flow Imaging in the Diagnosis of Hepatic Carcinoma

Objective:To study the application of color Doppler flow imaging(CDFI) in the diagnosis of hepatic carcinoma.Method:ATL3000 CDFI was used to examine hepar space occupying lesion of 27 cases with the primary carcinoma of liver (HCC) and 21 cases with metastatic hepatic carcinoma (MHC).The used indexes were Vmax,RI,A/B and FV.Results:There were significant differenc es in the detectable rates of the blood flow signals.The blood flow of the patie nts with HCC coul d reach the center of the tumor,and that of the patients with MHC was mostly in the outboard of the tumor.Conclusion:The hemodynamics of HCC and MHC shows appar ent differences and CDFI plays an important role in diagnosis and confirming dia gnosis of HCC and MHC.
