Methods:The imaging appearances of 110 patients with SARS were retrospectively analyzed.All the patients had comparatively complete chest film data and additional CT was performed in 5 cases. Results:The appearances on plain film were variable, and present mainly with two types of the changes:parenchymal and interstitial exudation. According to their initial radiographic appearances and progression,the patterns of le- sions were categorized to five subtypes: ¹ pure focal lesion( n= 34) as the single focal lesion in early stage,which expandedor did not ob- viously enlarge in the series radiography. º foca-l extensive lesion(n= 20) ,which initially appeared as single focal consolidation and pro- gressed quickly and extensively. » multiple lesions( n= 28) , whic
