摘要
本文报道了采用泛影葡胺对３０例肝脏肿瘤进行肝动脉动态声学造影的声像图结果。根据病变区与周围组织的回声变化，声像图结果可分为三型，Ａ型：病变区快进快出的增强呈“满天星征”，在２２例原发性肝癌中有１９例显示此征，占８６％；Ｂ型：病灶区边缘结节状强化，并向中心扩散，在５例肝海绵状血管瘤中见于４例；Ｃ型：病灶周边回声增强，见于肝转移癌３例及巨块型肝癌１例。此外我们还分析了声像图结果与病理的联系，并指出这种超声造影的方法弥补了Ｘ线血管造影与彩色多普勒血流显像（ＣＤＦＩ）中的一些不足之处。
This article reported the result of the enhancement of 30 cases with hepatic tumor on sonogram by injecting 60% urographin into the hepatic artery as a contrast material. Enhanced sonograms were classified into three patterns according to the relative change of the echo levels between the tumors and the nontumors parenchyma of the liver as a result of enhancement, Type A: urographin goes in and out tapidly and the enhancement is just like'the sign of the stars spread out the sky', 19 of the 22 patients with hepatocellular carcinoma exhibit this pattern, with an agreement rate 86%; Type B: the marginal nodous hyperechoic moves into center of the tumor, this pattern was seen in 4 among 5 patients with hepatic cavernous hemangioma, with an agreement rate 80%; Type C: the pattern of hyperechoic rim is observed in 3 cases of metestatic carcinoma and 1 case of big hepatocellular carcinoma. In addition, we also analyzed the relationship between sonogram and pathology. Furthermore, comparison of the enhanced ultrasonograph with X-ray angiography and color Doppler flow imaging can illustrate the advantage of this method.
