摘　　要：目的探讨大型方舱医院普通型Omicron感染者的胸部CT特征,旨在提高对普通型新型冠状病毒肺炎(COVID-19)CT表现的认识。方法回顾性分析上海国家会展中心方舱医院收治的381例普通型Omicron感染者的胸部CT特征。评估内容:病变分布(右/左肺,上/中/下叶,胸膜下/支气管血管周围)、范围(单/双肺,肺叶数)、肺实质受累征象(磨玻璃密度、实变、条索)、气管受累征象(小叶中心结节、树芽征、支气管管壁增厚及黏液栓塞)。结果381例患者中,300例>50岁。病变分布:以右肺和/或左肺下叶受累多见(298例),且主要分布在胸膜下(320例)。病变范围:累及单肺195例,双肺149例,307例受累不超过3个肺叶。病变以肺实质受累为主,磨玻璃密度359例,实变51例,条索55例;少数患者出现气道受累征象,小叶中心结节18例、树芽征11例、支气管管壁增厚及粘液栓塞7例。结论普通型COVID-19多见于50岁以上的中老年人,胸部CT以双肺下叶胸膜下磨玻璃密度为主,伴或不伴实变,支气管受累征象少见。Objective To investigate the chest CT features of patients with moderate novel coronavirus pneumonia(COVID-19)caused by Omicron variant in large shelter hospitals,aimed to improve the understanding of the CT findings of moderate COVID-19.Methods The chest CT features of 381 patients with moderate COVID-19 of Omicron variant were retrospectively analyzed in the Fangcang shelter hospital of National Exhibition and Convention Center.The evaluation contents include:lesion distribution(right/left lung,upper/middle/lower lobe,subpleural/peribronchovascular type),range(bilateral/unilateral,number of lobes),signs of lung parenchyma involvement(ground-glass opacities,consolidation,strip),signs of airway involvement(centrilobular nodules,tree in bud nodules,bronchial wall thickening and mucus embolism).Results Among 381 cases,300 cases were over 50 years old.Lesions distribution:The lesions were mostly involved in the lower lobe of the right lung and/or the left lung(298 cases),and were mainly peripheral-distributed(320 cases).Lesions range:195 cases(51.2%)were bilateral involvement,149 cases(48.8%)were unilateral involvement,and 307 cases were involved no more than three lung lobes.The lesions were mainly involved lung parenchyma,with ground glass density in 359 cases,consolidation in 51 cases,and stripe in 55 cases.Some patients showed signs of airway involvement,with centrilobular nodules in 18 cases,tree in bud nodules in 11 cases,bronchial wall thickening and mucus embolism in 7 cases.Conclusion Moderate COVID-19 were mostly found in middle-aged and older adults over 50 years old.Chest CT showed ground-glass opacities distributed in the subpleural area of the lower lobes,with or without consolidation,and the signs of airway involvement were rare.
