目的 探讨肝硬化及其继发性改 变的CT影像学特征，提高对其认识及诊断 水平。方法 选取经本院临床确诊的肝硬 化病患50例，进行螺旋CT扫描，并对肝硬 化及其继发性改变的CT影像学检查进行回 顾性分析。结果 50例肝硬化中，10例(占 20%)肝脏大小改变，12例(占24%)肝脏表 面呈现波浪状，25例(占50%)患者肝密度 减低，16例(占32%)患者肝密度增高，13 例(占26%)具有脾大现象，15例(占30%)具 有腹水现象，20例(占40%)具有门静高压 现象。其中48例肝硬化CT扫描异常，均正 确诊断；2例由于不具有典型肝硬化而被 延误诊断。结论 肝硬化及其继发性改变 胸部异常表现多样，通过CT扫描检查发现 异常，有助于判断肝硬化及其继发性改变 病情，并指导临床诊断与治疗。

Objective To study the CT imaging characteristics of liver cirrhosis and its secondary change to improve the understanding and diagnostic level. Methods 50 liver cirrhosis patient were selected in our hospital clinical diagnosis, and CT imaging of liver cirrhosis and its secondary change were retrospectively analyzed. Results 50 cases of liver cirrhosis, 10 cases (20%) of the liver size had changed, 12 cases (24%) of the liver surface were wavy, 25 cases (50%) in patients with liver density decreased, 16 cases (32%) in patients with liver density increased, 13 cases (26%) had splenomegaly, 15 cases (30%) had ascites, and 20 cases (40%) had door static pressure phenomenon.Among them, 48 cases of cirrhosis of the liver CT scan is unusual, and had correct diagnosis, 2 cases were delayed due to no typical cirrhosis diagnosis. Conclusion Liver cirrhosis and its secondary change abnormal chest in diversity, and CT scan of them was abnormal. CT scan can help determine cirrhosis of the liver and its secondary change condition, and guide clinical diagnosis and treatment.
