摘要
目的探讨64层螺旋CT直接法静脉造影在下肢深静脉血栓(DVT)中的诊断价值。资料与方法19例临床怀疑DVT患者行64层螺旋CT直接法下肢深静脉造影检查,着重分析DVT的CT征象,探讨影响其诊断准确性的因素。结果64层螺旋CT直接法静脉造影对DVT显示较好,在15例患者中共发现DVT25处,分别位于髂静脉(4)、股静脉(7)、腘静脉(9)和腓静脉(5)。结论64层螺旋CT直接法下肢深静脉造影结合多种后处理技术可以清楚显示DVT,具有较高的临床应用价值。
Objective To evaluate the diagnostic value of direct 64-slice CT venography(CTV) in the detection of deep venous thrombosis(DVT) of lower extremities.Materials and Methods 19 patients with suspicious DVT of the lower extremities underwent direct CTV using 64-slice CT scanner.Results Direct CTV detected DVT in 15 patients.The DVT detected by CTV were located in 4 iliac veins,7 femoral veins,9 popliteal veins,and 5 calf veins.Conclu-sion Combined with postprocessing techniques,direct CTV has high values in the detection of lower extremities DVT.
