【摘要】 目的：比较电子计算机断层扫描(CT)和核磁共振成像(MR)肺动脉成像诊断急性肺动脉栓塞(PE)的效能。方法：回顾性分析2016年8月-2018年8月笔者所在医院住院部收治的76例经CT或MR肺动脉成像检查的PE患者，根据检查方法的不同分为CT组39例和MR组37例，分析CT及MR对PE的诊断效能。结果：CT组的诊断准确率为89.74%，高于MR组的70.27%，差异有统计学意义(P<0.05);CT组及MR组对PE直接征象诊断准确率比较，差异均无统计学意义(P>0.05)。结论：CT诊断PE的诊断效能高于MR，值得应用。

    [Abstract] Objective： To compare diagnostic efficiency of computed tomography (CT) and magnetic resonance (MR) pulmonary artery imaging for acute pulmonary embolism (PE). Method： A retrospective analysis was performed on 76 PE patients who underwent CT or MR pulmonary artery imaging and were admitted to inpatient department of our hospital from August 2016 to August 2018. They were divided into CT group (n=39) and MR group (n=37) according to different examination methods. The diagnostic efficiency of CT and MR for PE was analyzed. Result： The accuracy of CT group for diagnosis of PE was 89.74% ......
