Methods: 80 patients with peripheral lung masses were selected from June 2015 to June 2013, and the CT enhanced scan, MRI and CT enhanced scan were performed in patients. Results the diagnostic sensitivity of:CT was 82.98%, specificity was 53.85%, sensitivity of MRI was 75.47%, specificity was 58.82%, sensitivity and specificity of CT enhanced scan was 80%, specificity was 92.86%, sensitivity and specificity of CT enhanced scan was not significantly different (P gt; 0.05). Conclusion: CT enhanced scan and MRI scan were applied in differential diagnosis of peripheral lung masses. It can significantly improve the diagnostic sensitivity and specificity, and it is also important for the diagnosis of benign and malignant peripheral lung masses. 　　Key words: CT enhanced scan; MRI diagnosis; peripheral lung mass; clinical value 　　肺肿块是常见肺部病变疾病，其发生原因与肺部炎症、恶性肿瘤以及肺结核具有紧密联系[1]。肺部肿块患者如果能够得到早期诊断和有效治疗，可显著提高临床治疗效果，并且对比病情的控制具有显著促进作用[2]。以往一般采用痰液和纤维支气管镜对肺肿块患者进行诊断，然而痰液诊断方法对于干咳无痰型患者无法检出，纤维支气管镜不能够到达的周围型肺肿块，所以上述方法的使用范围不大[3]。本次研究选取我院收治的80例周围型肺肿块患者分别采用CT增强扫描、MRI诊断以及CT增强扫描联合MRI诊断，对比临床诊断结果。现总结示下。 　　1 资料与方法 　　1.1 一般资料 选取2013年6月至2015年6月我院收治的80例周围型肺肿块患者，其中男44例，女36例；年龄32-75岁
