目的探讨增强CT协同磁共振扫描在周围型肺肿块诊断中的应用价值.方法选取2011年8月~2013年12月于我院经CT肺部平扫诊断为周围性肺肿块患者60例作为研究对象,观察增强CT、MRI、增强CT+MRI三种检查方式的影像资料,分析三种方式对周围型肺肿块的敏感性与特异性.结果增强CT+MRI诊断方式的敏感性达到95%,与增强CT和MRI比较差异有统计学意义(P〈0.05);增强CT+MRI诊断方式的特异性要明显高于其余两种方式(P〈0.05).结论增强CT协同磁共振扫描在周围型肺肿块鉴别诊断中,具备较高敏感性与特异性,能够较好地帮助肺肿块良恶性的判断. “,”Objective To investigate the enhanced CT collaborative application value of magnetic resonance scanning in the diagnosis of peripheral pulmonary masses of. Methods From 2011 August-2013 year in December in our hospital with lung CT scan diagnosis for patients with peripheral pulmonary masses in 60 cases as the research object, Results Enhance the sensitivity of CT+MRI diagnosis method reached 95%, Conclusion Enhanced collaborative CT magnetic resonance scanning in the differential diagnosis of peripheral pulmonary masses,with high sensitivity and specificity.
