【摘要】 目的 从技术应用方面探讨16层螺旋CT对肺栓塞血管造影的价值。方法 17例肺动脉栓塞(简称肺栓塞)患者行血管造影(CTA)，CT后处理采用多平面重建(MPR)、最大密度投影(MIP)及容积再现(VR)。结果 肺动脉增强后的CT值显著高于栓子的CT值，CTA对肺栓塞可清晰显示。结论 多层螺旋CT(MSCT)对肺栓塞的诊断具有明显的技术优势。

    【Abstract】 Objective To study the application of 16-detector multi-slice spiral CT (MSCT) angiography for pulmonary embolism.Methods Seventeen suspected pulmonary embolism (PE) patients were performed pulmonary artery angiography in 16-detector MSCT.Postprocessing included multiplanar reformation (MPR),maximum intensity projection (MIP),and volume rendering (VR).Results The CT value of enhanced pulmonary artery was obviously higher than the thrombus.CTA could distinctly deplay thrombus.Conclusion 16-detector MSCT angiography have obvious technique advantage in the diagnosis of PE. ......
