多层螺旋CT对肝脏泡状棘球蚴病累及脉管系统的诊断价值

Diagnostic Value of Vascular System Damage in Hepatic Alveolar Echinococcosis with Multi-slice Spiral CT

目的应用多层螺旋CT扫描,对肝脏泡状棘球蚴病患者脉管系统损害情况进行评价。方法所有病例均行多层螺旋CT扫描,分析原始图像及重建图像,评价脉管系统受累情况,并将肝血管受累情况与手术所见行对照分析。结果 MSCT图像显示117例患者中59例病变累及肝动脉、肝静脉或门静脉,与手术所见对比研究,多层螺旋CT对肝血管评价的敏感度、特异度及阳性预测值分别为96%、93%和93%。另外31例患者存在肝内胆道系统不同程度扩张。结论 MSCT可用于分析肝脏泡状棘球蚴病患者脉管系统受累情况,为正确诊断及合理治疗提供影像学依据。

Objective Assess Vascular system damage in Hepatic alveolar echinococcosis with Spiral CT scan and enhanced scan.Methods All patients with HAE were performed by MSCT, Vascular system damage were assessed by analyzing the raw data and reconstruction, Correlated studies were made between the Hepatic vascular involvement in CT features and Surgical findings.Results MSCT depicted that the lesion cause damage in Hepatic artery, hepatic vein or portal vein in 59 of all 117 cases. The sensitivity, specificity and positive prediction value for evaluating the vascular system were 96%, 93% and 93%. There are 31 cases who have Intrahepatic bile duct dilatation.Conclusion MSCT can be used to analyze vascular system involvement in HAE, providing a basis for the correct diagnosis and appropriate treatment.
