目的 探讨合并胆管癌栓的肝细 胞癌CT影像特征。方法 收集我院2007- 2015年期间诊治合并胆管癌栓的肝细胞癌 患者40例，选取同期诊治未合并胆管癌栓 的肝细胞癌患者43例作为对照组。将两组 病例原发灶CT平扫与增强扫描影像特征进 行对比，且把相关数据进行统计学分析。 结果 病例组与对照组相比，病灶的分 布、形态、边缘、平扫及增强扫描病灶密 度、强化特征之间差异均存在统计学意义 (P<0.05)。结论 对合并胆管癌栓的肝细 胞癌CT影像特征的认知，有助其诊断率的 提高；病理生理学特征的影像学研究；临 床治疗方案的制定及病情的评估。

Objective To analyze CT image characteristics of hepatocellular carcinoma associated with bile duct tumor thrombi. Methods 40 HCC patients with BDTT who underwent surgical treatment during 2007?2015 were studied, 43 HCC patients without BDTT were selected as a control group. The characteristics of CT plain and strengthening scan image from primary lesion of these two groups were compared to make statistical analysis. Results After comparing, there is statistical significance (P<0.05) in the difference between focus distributing. shape.edge, the density of plain&enhancing scan, intensified characteristics. Conclusion The knowledge for CT image characteristics of HCC with BDTT is conducive to improve diagnosis rate, Imageology reseach to pathophysiological characteristics, treatment plan making and illness evaluation.
