摘　　要：目的:探讨多层螺旋CTPA及后处理技术对肺动脉栓塞的诊断及临床应用价值。方法:回顾性分析40例经多层螺旋CTPA确诊为肺动脉栓塞的影像资料,并应用MPR、MIP、VR等后处理方法不同角度显示肺动脉及其栓子情况,观察肺动脉栓塞的征象,10例经临床治疗后行CTPA复查并与临床结果对照指导治疗。结果:40例肺动脉栓塞(PE)病例中,中央型PE32例,周围型PE8例。肺动脉内栓子表现为中心型、偏心型及闭塞型的充盈缺损。经治疗复查CTPA显示栓子变小或消失。结论:MSCTPA已成为诊断肺动脉栓塞的可靠方法,并为肺动脉栓塞的治疗提供必要的指导。Objective：To discuss the diagnosis of multi-slice spiral CT pulmonary angiography with the restructure methods in pulmonary embolism（PE）,to evaluate the application of CTPA in clinical diagnosis and treatment.Methods：Informations of 40 patients with PE verified by CTPA were retrospectively analyzed.Displaying the pulmonary artery and the embolism with the restructure methods such as MPR,MIP,VR and so on,then observing the signs of PE,10 patients with therapied PE were examined by CTPA again,then comparing the results with the clinic and instructing the therapy.Results：In 40 patients with PE,centeral pulmonary embolism were 32 cases and peripheral pulmonary embolism were 8 cases.The embolism in pulmonary artery showed different filling defect signs,including central type,partial type and obstructed type.The embolisms in CTPA became small or disappeared after therapy.Conclusion：Multi-silce spiral CT pulmonary angiography was a reliable method in the diagnosis of PE,and it can provide necessary direction for the therapy of PE.
