摘　　要：目的:探讨肺动脉栓塞的多层螺旋CT检查方法。方法:多层螺旋CT对临床疑似肺动脉栓塞的15例进行双期扫描,获得的数据传至工作站运用MPR、VR、CPR、MIP技术后处理。结果:所有病例均获得满意图像,15例患者共累及34处肺动脉及其分支,其中右肺动脉血栓者6例(17.6%),左肺动脉血栓者7例(20.6%),肺叶动脉血栓者12例(35.3%),肺段动脉血栓者各8例(23.5%),亚肺段肺动脉血栓者1例(2.9%)。结论:MSCT及CTA是诊断肺动脉栓塞有效、快速、安全的影像学方法。Objective：To study the Multi-slice Helical CT detection methods in the pulmonary embolism. Methods： 15 suspected patients with pulmonary embolism were performed with dual-phase enhanced CT scan and all the data were reconstructed by MPR, VR, CPR and MIP in the workstop. Results：All cases were acquired content imaging, and 34 branches of pulmonary embolism were identified in 15 cases： right pulmonary arteries in 6 cases （17.6%）, left pulmonary arteries in 7 cases （20.6%）, lobar arteries in 12 cases （35.3%）, segmental arteries in 8 cases （23.5%）, subsegmental artery in 1 case （2.9%）. Conclusion： MSCT and CrA are the effective immediate, and safe methods for the diagnosis of pulmonary embolism.
