| 摘 要： | 本文观察分析了肝癌侵犯门静脉，在门脉分支及主干内形成癌栓后的ＣＴ影像特征。发现４６例中有４１例（９１％）有门脉增宽，此征象在ＣＴ图像上容易发现和测量出，可作为门脉癌栓的辅助诊断依据；同时ＣＴ平扫可以发现早期新形成的栓子，其特点是增宽的门脉内高密度结节影，ＣＴ值平均５６±７·８Ｈｕ；另外增强扫描可显示出平扫低密度而无增强表现的癌栓影。同时对上述各征象的产生机制进行了分析。

| Abstract: | Hepatocellar carcinoma(HCC) tends to invade the portal venous system and, to a lesser entent, the hepatic veins.Plan computed tomography (CT) can show the endovenous tumors directly by intra luminal high density knot, most often combined with dilatation of the portal venous branch or main trunk.. And intraluminal filling defect can usually be distinguished by means of contract material-enhanced CT. |
