摘　　要：目的：探讨ＣＤＦＩ对肝癌介入化疗栓塞（ＴＡＥ）前后肝血供及肿瘤血供的表现特点，评价其治疗效果。材料和方法：ＣＤＦＩ观察１９９５～１９９８年４８例肝癌（ＴＡＥ）前后肿瘤的血供情况、肝动脉血流动力学改变。结果：肝癌主要由肝动脉供血，少部分由门静脉供血； ＴＡＥ后肝动脉收缩期最大流速（ Ｖｍａｘ）明显下降，肿瘤内部及周边动脉血流明显减少； ＴＡＥ后肿瘤也明显减小。结论：ＴＡＥ前后，应用ＣＤＦＩ对肿瘤血供、肝动脉血流动力学改变进行观察分析，可以给ＴＡＥ的预后提供重要指标，为下一步重复治疗提供依据。ＣＤＦＩ是目前肝癌化疗栓塞术治疗前后最好的影像检查方法。Purpose: In order to determine the therapeutic efficacy of transcatheter hepatic artery embolization, color Doppler flow imaging (CDFI) was used to study the characteristic of hepatic and tumor blood supply before and after TAE. Materials and Method: we studied the tumor blood supply and hepatic hemodynamic changesin 48 HCC cases before and after TAE by CDFI. Result: Hepatic artery was the major blood supply for HCC. The maximal blood flow speed (Vmax) and blood supply around the tumor were evidently decreased after TAE, the size of the tumor was also decreased. Conclusion: The analysis of tumor blood supply and hepatic hemedynamics with CDFI before and after TAE can provide an important guideline for prognosis of HCC and repeat therapy after TAE. The CDFI might be the best imaging method in detecting blood flow change of HCC after TAE.
