摘　　要：目的:探讨64层螺旋CT血管成像在诊断肺动脉栓塞中的价值。方法:回顾性分析19例临床确诊为肺动脉栓塞的64层螺旋CT肺动脉成像资料,并用最大密度投影(MIP)、多平面重组(MPR)、容积再现(VR)等方法显示肺动脉。结果:19例患者中,其中左右肺动脉栓塞有8支,叶肺动脉栓塞27支,段及亚段肺动脉栓塞56支。偏心型41支,闭塞型38支,中央型8支,附壁环形型4支。结论:64层螺旋CT肺动脉成像可作为肺动脉栓塞诊断的首选方法。Objective：Explore the clinical value of 64-slice spiral CT in the diagnosis of pulmonary embolism（PE）.Methods：19 patients with pulmonary embolism（PE） underwent 64-slice spiral CT pulmonary angiography（CTPA） were analyzed retrospectively.2D and 3D image post-processing techniques（MIP,MPR and VRT included） were used to access the pulmonary artery.Results：Among 19 patients,91 thrombosed pulmonary arterial branches were displayed by CTPA,including 8 left and right main pulmonary arteriae,27 lobar arteriae,56 segmental or subsegmental arteriae.41 of which were eccentric,38 of which were complete occlusion,8 of which were central,4 of which were annular mural thrombus.Conclusion：64-slice spiral CT is an important examination in the diagnosis of pulmonary embolism（PE）.
