新型冠状病毒(2019-nCoV)感染的肺炎临床特征及影像学表现

Radiologic Features of Patients with 2019-nCoV Infection

2019年12月起,新型冠状病毒(2019-nCoV)肺炎在武汉市爆发流行,并迅速传播到全国和全世界。至今全国已累计报告确诊病例超过2万例,其主要原因是病毒传染力强、潜伏期长。2019-nCoV肺炎CT表现多为双肺多发磨玻璃密度影(GGO)。以双肺胸膜下分布为主,可伴空气支气管征、小叶间隔增厚和胸膜增厚。极少数或少数伴胸腔积液或淋巴结肿大。基于病理分期的新型冠状病毒性肺炎可分为早期、进展期与重症期3期。结合胸部影像学检查与临床和实验室结果有利于2019-nCoV肺炎患者的早期筛查和早期防控。

Since December 2019,a new pneumonia of 2019-nCoVcause?broke out in Wuhan city,and the infection has spread rapidly in China and worldwide.Up to now,morethan 20000 cases of 2019-nCoV infections were reported in China,which mainly because that the pathogenic virus has a high infectivity and a long incubation period.The predominant pattern of CT findings of patients with 2019-nCoV infections include bilateral ground-glass opacities(GGO)of the subpleural lung,air bronchograms,interlobular/septal thickening and thickening of the adjacent pleura.The less common CT findings were pleural?effusion?and lymphadenopathy.Based on pathological stage,the 2019-nCoV infections in CT can be divided into early stage,progressive stage and severe stage.Combining imaging features with clinical and laboratory findings can help make the early diagnosis andtimelyprevention of 2019-nCoV infection.
