多层螺旋CT扫描诊断肺动脉栓塞的应用价值

Investigation on the imaging features and value of multilayer spiral CT in diagnosis of pulmonary embolism

目的:探讨肺动脉栓塞患者的CT影像诊断价值。方法:回顾性分析22例临床怀疑为肺动脉栓塞的患者利用16排螺旋CT行肺动脉成像检查的影像学资料。结果:22例患者的肺动脉栓塞部位及范围均能显示,其中肺动脉栓塞10例,肺叶动脉栓塞7例,肺段及段以下动脉栓塞5例。22例患者中只有4例为单支动脉栓塞。结论:多层螺旋CT肺动脉成像作为一种无创性检查方法,能为肺动脉栓塞诊断提供直接、丰富的影像诊断细节,并能在治疗后较好地评价溶栓效果。

Objective： To investigate the diagnostic valuation of multilayer spiral CT pulmonary angiography in pulmonary embolism. Methods： A retrospective analysis 22 cases of pulmonary embolism were performed by 16 slice spiral CT diagnosis, The volume data of all cases were reconstructed for image post-processing with multi-plane reconstruction, maximum intensity projection and volume rendering. Results： Pulmonary embolism in patients with 22 cases,pulmonary artery and its branches remobilization of 22 cases were demonstrated well by MSCTA.Conclusion： The 16 slice spiral CT in the diagnosis of pulmonary embolism in a safe, rapid, high sensitivity, reliable diagnosis advantages, has been used as first choice of imaging diagnosis of pulmonary embolism diagnosis methods. It is worthy of wide clinical application.
