摘要
目的:研究CT肺动脉造影(CTPA)与磁共振成像(MRI)对肺动脉栓塞的临床诊断价值。方法:选取医院收治的79例疑似肺动脉栓塞患者,均进行CTPA和MRI检查,分析两种检查方式对肺动脉栓塞的检出率,比较CTPA与MRI检查的诊断效能。结果:在79例患者中病理检查确诊为肺动脉栓塞58例(占73.42%),CTPA诊断肺动脉栓塞阳性患者49例(占62.03%),阴性患者30例(占37.97%),与病理检查对比阳性检出率无差异。MRI诊断肺动脉栓塞阳性患者55例(占69.62%),阴性患者24例(占30.38%),与病理检查对比阳性检出率无差异。MRI对肺动脉栓塞检测的灵敏度、特异度、阳性预测值和阴性预测值分别为89.66%、85.71%、94.55%和75.00%,均高于CTPA检查的79.31%、61.90%、83.67%和43.33%,差异有统计学意义(x^2=4.086,x^2=14.662,x^2=6.099,x^2=20.757;P<0.05)。结论:MRI对肺动脉栓塞的诊断效能更高,具有较高的临床应用价值。
Objective:To study the clinically diagnostic value of CT pulmonary angiography(CTPA)and magnetic resonance imaging(MRI)for pulmonary artery embolism.Methods:79 patients with suspected pulmonary artery embolism who received treatment in hospital were selected,and they were examined by CTPA and MRI,respectively.The detection rates of two examination methods for pulmonary artery embolism were analyzed,and the diagnostic efficiency of the two methods were further compared.Results:In 79 patients,58 cases(73.42%)were diagnosed as pulmonary artery embolism by pathological examination.49 positive cases(62.03%)and 30 negative cases(37.97%)of pulmonary artery embolism were diagnosed by CTPA.There was no significant difference in the positive detection rate between CTPA and pathological examination.55 positive cases(69.62%)and 24 negative cases(30.38%)of pulmonary artery embolism were diagnosed by MRI,and there was no significant difference in the positive detection rate between MRI and pathological examination.The sensitivity,specificity,positive predictive value and negative predictive value of MRI in detecting pulmonary artery embolism were 89.66%,85.71%,94.55%and 75.00%respectively,which were significantly higher than those(79.31%,61.90%,83.67%and 43.33%)of CTPA(x^2=4.086,x^2=14.662,x^2=6.099,x^2=20.757,P<0.05).Conclusion:MRI has more diagnostic efficiency for pulmonary artery embolism and it has higher value in clinical application.
