摘要：

目的 分析肺部真菌感染的CT诊断价值及影像学特征。方法 选取我院在2015年1月至2015年12月收治的疑似肺部真菌感染患者50 例作为研究对象，对所有患者均进行X线片检查后进行CT诊断，检查结果分别与实验室病理检查结果 对比，并比较两种检查方法的准确率、灵敏度和特异度。结果 CT检查对肺部真菌感染的准确率为92.00%（46/50），灵敏度为 93.33%（42/45），特异度为80.00%（4/5）；X线片检查对肺部真菌感染的准确率为86.00%（43/50），灵敏度为88.89%（40/45），特异度为60.00%（3/5）。CT检查的准确率稍高于X线片检查，但差异无统计学意义（P>0.05）；CT检查的灵敏度、特异度均明 显优于X线片检查（P<0.05）。真菌感染特征主要有肺部炎症实变，结节和肿块，磨玻璃状的阴影，曲霉菌属感染，淋巴结肿大。结论 对肺部真菌感染患者实施CT检查，具有较好的临床诊断价值，可以为临床诊疗提供可靠的参考依据，值得推广。

ABSTRACT: Objective To explore diagnostic value and imaging features of CT on pulmonary fungal infection. Methods Fifty cases of patients suspected pulmonary fungal infection from January 2015 to September 2015 were selected as the research objects. All the patients received X ray examination and the CT diagnosis. Laboratory pathologic examination results and the X ray examination and CT diagnosis results, and the accuracy, sensitivity and specificity of the two methods were compared. Results The accuracy, sensibility and specificity of CT diagnosis were 92.00% (46/50), 93.33% (42/45), 80.00% (4/5), which were 86.00% (43/50), 88.89% (40/45), 60.00% (3/5) by X ray examination; the accuracy of the CT diagnosis was slightly higher than that of the X ray examination, but the difference was not significant (P<0.05). The sensibility and specificity of CT diagnosis were higher than those of X ray examination (P>0.05). The main characteristics of fungal infection were consolidation of the lung inflammation, nodules and lumps, ground glass-like shadows, aspergillus infection and lymph nodes. Conclusion CT examination has a good clinical diagnostic value in patients with pulmonary fungal infection, which can provide a reliable reference for clinical diagnosis and treatment. It is worth of promoting.
