CT肺动脉造影与MR诊断肺动脉栓塞的临床价值分析

The Diagnosis to the Clinical Value of CT Pulmonary Angiography and MR in Thepulmonary Embolism

目的对比研究CT肺动脉造影、MR诊断肺栓塞效用。方法开展前瞻性研究,2013年1月—2016年7月,方便选择内蒙古呼伦贝尔市扎赉诺尔区人民医院收治的疑似肺栓塞患者115例,采用MR、CT诊断。结果 MR肺段动脉显像成功率95.8%(2 534/2 645),高于CT 87.4%(2 311/2 645),MR诊断敏感性100.0%、特异度97.6%高于CT诊断62.2%、75.6%,MR诊断完全栓塞、部分栓塞检出率分别为97.3%、96.5%高于CT诊断89.0%、56.14%,差异有统计学意义(P<0.05)。结论 MR诊断肺动脉栓塞效果更好。

Objective To study the CT pulmonary angiography in diagnosis of pulmonary embolism, MR utility. Methods To carry out prospective studies, from January 2013 to July 2016, Convenient selection zhalainuoer District People＇s Hospital of Hulun Buir Inner Mongolia, 115 suspected pulmonary embolism patients were selected from the patients,using MR, CT diagnosis. Results MR pulmonary arteries imaging（2 534/2 645）, the success rate was 95.8% higher than that of CT 87.4%（2311/2 645）. MR sensitivity was 100.0%, specificity was 97.6% higher than that of CT 62.2%, 75.6%, MR in the diagnosis of complete embolization, partial embolization rate was 97.3%, 96.5% higher than CT 89.0%, 56.1%, the difference was statistically significant（P〈0.05）. Conclusion MR diagnosis pulmonary embolism effect is better.
