    【摘要】目的：探索慢阻肺合并肺间质纤维化病症运用CT和传统X线诊断价值。方法：筛选我院2019年1月—2021年9月收治的疑似(慢阻肺+肺间质纤维化)患者为研究对象(确诊76例)，对患者分别行CT检查与传统X线检查，计算诊断符合率、灵敏度、特异度与不同程度病症检出率，观察影像学特征。结果：80例疑似慢阻肺合并肺间质纤维化患者(综合病理确诊76例)，传统X线检出阳性70例，真阳性67例，阴性10例，真阴性1例；CT诊断检出阳性76例，真阳性75例，阴性4例，真阴性3例，传统X线诊断符合率、灵敏度、特异度(85.00%、88.16%、25.00%)低于CT诊断(97.50%、98.68%、75.00%)，差异显著(P<0.05)。两种诊断方式在重度、中度病症检出无统计差异(P>0.05)，轻度患者诊断中传统X线诊断相比CT诊断差异显著(P<0.05)。结论：慢阻肺合并肺间质纤维化病症运用CT诊断准确率更高，获得清晰的影像学资料，为病症诊断提供支持，应用价值较高。
