摘　　要：目的探讨MR I透视触发造影剂团跟踪和动态增强磁共振血管成像(DCE-MRA)扫描技术在肺灌注和肺动脉血管造影中的应用价值。方法8例疑有肺栓塞的患者,应用MR I透视触发造影剂团跟踪和DCE-MRA扫描技术,行肺动脉血管造影和肺灌注成像。结果8例均成功进行肺动脉血管造影和肺灌注扫描,其中2例正常,6例发现肺动脉血栓形成,并有明确动态显示的局部肺叶灌注异常。结论MR I透视触发造影剂团跟踪和DCE-MRA扫描技术的应用,可1次注射造影剂既发现了肺动脉内血栓,又可显示肺内灌注缺损,是较好的肺栓塞诊断方法。Objective To evaluate the value of fluoroscopic triggered bolustrak and dynamic contrast- enhanced magnetic resonance angiography （DCE - MRA） in pulmonary embolism （PE）. Methods MRI pulmonary artery angiography and pulmonary perfusion imaging using both MRI fluoroscopic triggered bolustrak and DCE - MRA imaging skills were performed in 8 cases with suspicious of PE underwent. Results All of 8 patients successfully enderwent MRI pulmonary artery angiography and DCE -MRA scanning. 2 patients were normalland PE was detected in other 6 cases and the local lung lobes were perfusion abnormal. Conclusion MRI fluoroscopic triggered bolustrak and DCE - MRA skills are good imging techniques in detection of PE.
