-
摘要: 目的：分析2019新型冠状病毒肺炎（COVID-19）胸部CT表现，为早期发现、诊断、隔离及治疗提供参考。方法：回顾性分析我院8例确诊COVID-19患者临床资料和胸部CT影像表现，重点观察CT病灶的密度、大小、形态、数目及分布情况。结果：8例患者均可见磨玻璃影（部分可见亚实性磨玻璃影）、其形态不一，数目较多，以双肺外周及下叶分布为主，并见小血管影增粗（n=8）、细网格影（铺路石征）（n=6）、支气管充气征（n=5）、支气管壁增厚（n=4）、条索影（n=3）等伴随征象。2例合并双肺下叶实变影，1例患者见微小结节，周围可见晕征。8例患者均未见胸腔积液及纵隔淋巴结肿大。结论：COVID-19胸部CT表现有一定特征性，胸部CT检查对患者的早期筛查起着重要作用。Abstract: Objective:To analyze the chest CT manifestations of 2019 novel coronavirus pneumonia (COVID-19), and to provide reference for early detection, diagnosis, isolation and treatment. Methods:The clinical data and chest CT findings of 8 patients with COVID-19 were analyzed retrospectively. The focused observations were on the density, size, shape, number and distribution of CT lesions. Results:The ground glass and partial ground glass shadow was found in 8 cases, which was mainly distributed in the lower lobes and peripheral areas of both lungs, which was accompanied by small vessel shadow thickening (n=8), fine mesh shadow (paving stone sign) (n=6), bronchi inflation sign (n=5), bronchi wall thickening (n=4), strip shadow (n=3). Two cases had consolidation of lower lobe of both lungs. In one patient, there was a small nodule and halo sign around. There was no pleural effusion or lymphadenopathy in 8 patients. Conclusion:CT findings of COVID-19 have certain characteristics. Chest CT plays an important role in early screening of patients.
