摘　　要：[目的]研究多排螺旋CT肺动脉造影在临床疑似肺栓塞患者诊断中的应用价值。[方法]对86例临床疑似或诊断肺动脉栓塞的患者行对比剂增强64排螺旋CT肺动脉造影扫描,在高分辨横轴位图像基础上,进行多层面(MPR)和最大密度投影(MIP)重建,对中央、叶、段、段间的肺血管的显示进行分析和评价。[结果]所有叶肺动脉均优化显示;8支段肺动脉为一般显示;42支段间肺动脉显示一般,15支段间肺动脉显示不清。86例患者中,28例显示明确的肺动脉血栓,其中21例显示存在段间肺动脉血栓,横轴位图像上甚至可以观察到更为细小(5级甚至以下)的肺动脉血栓。[结论]对比剂增强64排螺旋CT肺动脉造影技术作为一项诊断或排除疑似PE的工具,安全、简便、可行且经济。[Objective]To study the value of the 64-detector spiral CT pulmonary angiography in diagnosis of patients with clinically suspected pulmonary embolism（PE）.[Methods]86 patients with PE or suspected PE were detected with 64-detector spiral CT pulmonary angiography.and their images were ecconstructed by MPR and MIP on the basis of high resolution abscissa axis image.The images of main,lobar,segmental,and subsegmental arteries were analyzed and evalualed Ⅰ.[Results]All lobar arteries were well visualized,8 segmental arteries were suboptimally visualized.42 subsegmental arteries were suboptimally visualized.and 15 subsegmental arteries were well visualized in 21 patients.Smaller emboli（under the fifth grade）coule be visualized in axial images.[Conclusion]64-detector spirla CT pulmonary angiograsphy is a safe,convenient,feasible and cost-effective method in diagnosis of PE,and to exclude the suspected PE.
