摘　　要：本文通过对８４例肝癌、１６例肝海绵状血管瘤、３例肝炎性假瘤的超声多普勒检查并和血管造影结果对照，提出彩超及脉冲多普勒诊断肝癌的特异性指标：周边彩色血流篮状包绕征；病变内部多分支异常血流；脉冲血流频谱高于１００ｃｍ／ｓ，连续型频谱高于３０ｃｍ／ｓ；肝总动脉血流量大于７００ｍｌ／ｍｉｎ。描述了肝血管瘤的异常彩色血流特点：纤细、分支少、走行自然、由周边直接进入病变包膜下、流速低，均小于１０ｃｍ／ｓ。Dopplex Doppler and color Doppler flow imaging were used to detect blood flow of tumors and common hepatic arteries in 103 patients, including 84 primary hepatic carcinomas,16 hepatic hemangiomas and 3 inflammatory pseudocarcinomas.We found that follow significant characteristics only appeared in primary hepatic carcinomas, including: abnormal blood flow surrounding the tumor nodules called ″basket pattern″,many branchs blood flow within the tumor nodules.The velocity of those abnormal blood flow was higher than 100 cm/s in pulsative wave and 30 cm/s in high continuous wave. Blood flow volume in common hepatic arteries was higher than 700 ml/min. In contrast, there were no those characteristics in hemangiomas and inflammatory pseudocarcinomas.
