    摘 要:目的 了解原发性肝癌(HCC)和转移性肝癌(MHC)肿块及肝脏的彩色多普勒超声表现，为其诊断和鉴别诊断提供依据. 方法 彩色多普勒血流显像(CDFI)观察183个HCC肿块、96个MHC肿块，及其肝动脉、门静脉的血流情况，分别检测其最大血流速度(vmax )和阻力指数(RI).将两组资料分别分为小肝癌型、结节型及块状型进行对比分析. 结果 随着肿块增大，两组肿块血供增加.HCC以瘤内双重供血为主，vmax 和RI均随肿块增大而增高;MHC以瘤周双重供血为主，随肿块增大RI增高，三型肿块vmax 均为30cm·s-1 左右，随肿块增大无明显变化(P>0.05).两组患者肝动脉内径、vmax 随肿块增大而增加，HCC组RI无明显变化，MHC组RI随之增大.HCC组门静脉内径和vmax 随肿块增大无显著变化;而MHC组内径增加，vmax 却逐渐降低. 结论 原发性与转移性肝癌的肿块和肝脏血流动力学表现明显不同，CDFI对两者的诊断及鉴别诊断具有重要作用.
