本文应用彩色多普勒血流显像（ＣＤＦＩ）观察了３４例肝癌经肝动脉插管栓塞治疗中及化疗后肿瘤血供和声像图的变化特点以及二者之间的关系。提示肿瘤缩小程度由栓塞后血供减少情况而定，血供减少在先，肿瘤缩小在后，内部异常血流较周边血流减少早且明显。小结节较大的巨块型肝癌效果好。和肝动脉造影结果对照展示了ＣＤＦＩ在观察肝癌肿瘤血管及血流的准确性以及在全面观察、随诊经栓塞治疗的肝癌方面的优越性。 In this paper, color Doppler flow imaging (CDFI) was used to observe the characteristics of changes in blood supply and acoustic image of 34 cases of hepatocellular carcinoma after hepatic artery catheterization and embolization, and the relationship between them. It is suggested that the degree of tumor shrinkage is determined by the decrease in blood supply after embolization. The blood supply is reduced first, and the tumor is shrinking later. The internal abnormal blood flow is reduced earlier and significantly than peripheral blood flow. Larger nodules have a great effect on massive liver cancer. Comparing with the hepatic arteriography results, the superiority of CDFI in the observation of the accuracy of hepatoma tumor blood vessels and blood flow and the comprehensive observation and follow-up of embolization-treated liver cancer were demonstrated.
