摘　　要：目的　探讨急性传染性非典型肺炎的影像特征与分型。方法　通过回顾性分析和部分病理对照的方法对 10 5例传染性非典型肺炎的胸部X线片及CT片进行研究。结果　肺实质局部浸润占 2 3 .8% ,肺实质广泛浸润占 2 4.8% ;肺间质局部浸润占 11.4% ;肺间质广泛浸润占 18.1% ;混合浸润占 2 1.9%。结论　胸部X线片发现肺部浸润病灶是临床诊断急性传染性非典型肺炎的重要依据之一。根据肺部渗出病灶的类型可大致分为肺实质浸润、肺间质浸润、混合浸润三大类。结合流行病史或免疫学检查可与其他肺炎鉴别。Objective To explore the characteristics and classification of severe acute respiratory syndrome (SARS).Methods We analyzed the X-ray and CT photographs of 105 SARS patients retrospectively and partly compared the results pathologically.Results The analysis and comparisons showed local and extensive pulmonary parenchyma infiltrations took up 23.8% and 24.8% respectively;local and extensive pulmonary interstitial infiltrations took up 11.4% and 18.1% respectively;mixed infiltrations 21.9%.Conclusion Chest X-ray photographs, as one of key SARS diagnosis indications, are able to display the foci of pulmonary infiltrations, based on which we can classify the chest imaging generally into three categories: pulmonary parenchyma infiltration, pulmonary interstitial infiltration and mixed infiltration. SARS can be differentiated in diagnosis if we combine the X-ray and CT photographs with epidemic history or immunological examinations.
