目的探究双源CT在淋巴细胞 间质性肺炎患者临床诊断过程的应用价 值。方法 采用回顾性分析法，对本院 2014年6月-2016年6月期间收治的80例淋 巴细胞间质性肺炎患者的临床资料进行 分析、归纳和总结。根据患者诊断方式 的不同，将患者分为双源CT诊断组和病 理诊断组，对比两组患者在临床确诊率 上的差异。结果 双源CT组患者临床主要 症状为咳嗽咳痰23例，发热5例，胸闷 5例，肺部湿啰音、肺部呼吸音降低24 例，胸痛19例，无症状患者3例，与病理 组比较两组差异无统计学意义,P>0.05。 病理组患者的确诊率95.00%显著高于双 源CT组患者的75.00%，(P＜0.05)，组间 对比差异显著，具有统计学研究价值。 结论 使用高分辨率双源CT诊断淋巴细胞 间质性肺炎，有漏诊现象，可以结合病 理检查来提高临床确诊率，减少误诊、 漏诊现象。

Objective To investigate the application and diagnostic value of dual source CT in the clinical diagnosis of lymphocytic interstitial pneumonia. Methods The clinical data of 80 cases of lymphocytic interstitial pneumonia treated in our hospital from June 2014 to June 2016 were analyzed retrospectively and summarized. According to the different diagnostic methods, patients were divided into dual source CT diagnostic group and pathological diagnosis group, and the difference of clinical diagnosis rate between the two groups was compared. Results The main symptoms of the double source CT group were cough and expectoration (23 cases), fever(5 cases), chest tightness(5 cases), pulmonary rales and lung breath sounds reduced(24 cases), chest pain(19 cases), asymptomatic patients(3 cases), and symptoms of pathological group had no significant difference, P>0.05. The diagnosis rate of the pathological group was 95%, significantly higher than that of the dual source CT group (75%) (P<0.05), the difference between the two groups was statistically significant. Conclusion Misdiagnosis of Lymphocytic Interstitial Pneumonia by dualsource CT can be combined with pathological examination to improve the clinical diagnosis rate and reduce misdiagnosis and missed diagnosis.
