| 摘 要： | 目的探讨原发性肝癌门静脉癌栓（PVTT）多层螺旋CT血管成像（CTA）的影像特征及其诊断价值。方法对179例诊断为原发性肝癌的患者行多层螺旋CT扫描平扫和三期动态增强扫描，并行多平面重建（MPR）、最大密度投影（MIP）及容积再现（VRT）血管成像，选择其中合并PⅥT的87例患者比较其横轴位图像及CTA图像在诊断中的差异。结果轴位及CTA显示门静脉主干一级分支及二级分支PVTT无显著差异（P＞0．05），而二级以下分支PVTT显示有显著差异（P〈0．05）；CTA图像对于肿瘤供血动脉及侧支循环血管的显示较轴住图像立体、直观。结论多层螺旋CT动态增强扫描并血管重建，可提高较门静脉小分支的检出率，较好地多方位显示门静脉癌栓的位置、范围、程度及侧支血管，直接显示肿瘤与门静脉血管的关系。
