摘　　要：目的探讨64排螺旋CT在肺动脉栓塞诊断中的应用价值。方法回顾性分析64排螺旋CT对94例临床高度怀疑肺动脉栓塞的患者进行肺动脉造影,并将图像进行容积再现(VR)、多平面重组(MPR)和最大密度投影(MIP)等后处理,对38例诊断为肺动脉栓塞的患者进行影像学研究。结果通过CT肺动脉造影成像可充分观察到肺动脉栓塞的部位、形态、范围及栓子的大小。病变共累及肺动脉218支,其中左右肺动脉18支、叶肺动脉43支、段肺动脉82支、亚段肺动脉75支。结论 64排螺旋CT血管成像为肺动脉栓塞患者提供一种快捷、无创、准确且安全的诊断方法,并可作为肺动脉栓塞的首选检查方法。Objective To explore the value of multi-slice spiral CT angiography （MSCTA） in diagnosing pulmonary embolism （PE）. Methods Ninety-four cases of clinical height doubt PE were performed by MSCT pulmonary angiography. The volume data of all cases were analyzed retrospectively, which were reconstructed for image post-processing with multi-plane reconstruction （MPR）, maximum intensity projection （MIP） and volume rendering （VR）. Thirty-eight cases with correct diag-- nosis carried on image research. Results 64 MSCT pulmonary angiography could adequately observe the location, form, range and size of PE. The PE patients were found to be involved in 218 branches of puomonary afteries in all cases. Among them, there were 18 left and right pulmonary artery, 43 interlobar artery, 82 segmental pulmonary artery, and 75 subsegment ab puimonary artery. Conclusion The 64 MSCTA provides one kind of rapid, non-invasive, accurate and safe diagnosis method, and the examination may be the preferred to arterial PE patients.
