摘　　要：目的探讨C臂CT在腹部介入诊疗中的应用价值。方法 42例行腹部介入诊疗患者在常规DSA基础上行C臂CT检查,评价C臂CT是否提供额外影像信息及其对介入治疗方案的影响;其中25例与近期多层螺旋CT(MSCT)比较,评价其图像质量。结果在35例行介入治疗的患者中,68.6%(24/35)C臂CT在常规DSA基础上能提供额外影像信息,22.9%(8/35)影响了最初通过常规DSA制定的介入治疗方案;7例行肝动脉造影CT(CTHA)及经动脉门静脉造影CT(CTAP)检查患者,诊断均准确;C臂CT图像质量平均评分为2.62(稍差于MSCT)。结论在腹部介入诊疗中,C臂CT能提供较高质量的软组织断层影像,在常规DSA基础上提供较多额外影像信息,并影响介入方案的制定,有利于介入诊治。Objective To evaluate C-arm CT system equipped with a flat-panel detector in performing abdominal interventional treatment.Methods Both digital subtraction angiography（DSA） and C-arm CT scanning were performed in forty-two patients with abdominal diseases before the interventional procedures were carried out.The imaging findings of C-arm CT scans were analysed to see if CT scans provided any additional information,and the impact of any additional information provided by CT scans on the making of interventional therapeutic scheme was evaluated.The imaging quality of C-arm CT scanning of 25 cases were compared with that of multi-slice CT scanning performed not long before.Results Of 35 patients receiving interventional treatment,24（68.6%） got additional imaging information from C-arm CT scanning except the information obtained from conventional DSA.The initial therapeutic plan was influenced by the additional imaging information from C-arm CT scanning in 8 cases（22.9%）.The correct diagnosis was obtained in all 7 patients who received C-arm CT hepatic angiography and C-arm CT trans-arterial portovenography.The average score of C-arm CT image quality was 2.62.Conclusion C-arm CT scanning can provide cilinically acceptable soft tissue image quality and important additional image information,for this reason,in demonstrating the details of the target organs C-arm CT scanning is superior to DSA.Therefore,C-arm CT scanning is very helpful for the making of interventional procedures.
