摘　　要：目的:探讨新型冠状病毒肺炎(简称新冠肺炎)的初诊CT特征性表现,以及与流感病毒性肺炎的鉴别诊断。方法:收集临床确诊的8例新冠肺炎及10例流感病毒性肺炎的CT资料,分析2组肺内感染病灶的位置、分布、密度及形态。结果:2组病变分布方式(单肺分布、胸膜下分布、沿中轴支气管血管束分布)、支气管壁增厚及树芽征检出率比较差异均有统计学意义(均P<0.05)。结论:当胸部CT出现双肺胸膜下多发磨玻璃影或伴实变、有小叶内间隔增厚呈网格状表现,提示新冠肺炎。出现支气管壁增厚、树芽征、病灶沿中轴支气管血管束分布、伴胸腔积液及淋巴结肿大,新冠肺炎可能性不大。Objective:To investigate the initial CT characteristics of COVID-19 and the differential diagnosis with influenza virus pneumonia.Methods:CT imaging data of 8 cases of COVID-19 and 10 cases of influenza viral pneumonia were collected retrospectively,and the size,number,location,distribution,density and morphology of the pulmonary lesions were analyzed.Results:There were significant statistical differences in the lesions’distribution patterns,thickening of bronchial wall and bud signs between the two groups(all P<0.05).Conclusions:On chest CT images,it hints COVID-19 if multiple ground-glass shadows or mixed with consolidations are located in the subpleural areas of bilateral lungs,and accompanied with the thickening of interlobular septa.It suggests low possibly COVID-19 if pulmonary lesions distribute along the bronchovascular bundle,with bronchial wall thickening and bud signs,and accompanied by pleural effusion and lymph node enlargement.
