摘要
目的探讨大鼠肝癌血供的影像表现。方法对１２只大鼠肝癌模型进行彩色多普勒血流显像（ＣＤＦＩ）、肝动脉造影（ＨＡ）以及门静脉造影（ＨＰ）检查并与病理对照。结果２～３ｍｍ瘤结节多为门脉单一血供（Ⅰ型），细胞分化较高；３～５ｍｍ瘤结节多为肝动脉和门脉双重血供（Ⅱ型），细胞分化较高；＞５ｍｍ瘤结节主要为肝动脉血供，门脉仅在瘤周参与血供（Ⅲ型），细胞分化较差。ＣＤＦＩ在瘤结节周边及内部显示的血流代表了造影所见的肿瘤血管和（或）肿瘤染色。结论大鼠肝癌血供演变的影像表现对人类肝癌诊断、介入治疗途径选择以及疗效预测具有参考意义。
Objective\ To approach the image manifestations of liver tumor blood supply in rats. Methods\ An examination had been given to 12 rats with liver tumor by way of color Doppler flow imaging (CDFI), hepatic arteriography (HA) and hepatic portography (HP), and then contrasted with pathologies. Results\ 2￣3 mm tumor nodules were often of portal vein blood supply (type Ⅰ) and the cells splited up easily; 3￣5 mm tumor nodules were of both hepatic artery and portal vein blood supply (type Ⅱ) and the cells also splited up easily; >5 mm tumor nodules were mainly of liver artery blood supply, and the portal viens were only around the tumor, taking part in blood supply (type Ⅲ), the cells couldn't split up easily. The bloodstream showed around tumor nodules or in them by CDFI stands for tumor blood vessels and /or tumor stains seen by radiography. Conclusions\ From the above it has become obvious that the image manifestations of the evolution of blood supply of liver tumor in rats have proved to be of practical significance to diagnosis of human liver tumor, to preference of its treatment and to calculation of its curative effect.
