摘要
目的探讨新型冠状病毒肺炎(COVID-19)无症状感染者的胸部CT征象。资料与方法回顾性分析16例无任何临床可识别症状和体征、核酸检测阳性COVID-19患者的胸部CT特征及临床资料,纳入有明显临床症状、核酸检测阳性的28例患者作为对照,比较两组病灶累及范围、病灶形态、特征及肺部以外的影像学表现。结果与有症状组比较,无症状感染组病灶累及肺部范围较小,6例为单肺(50.0%),晕征比例较大(66.7%比3.5%),病灶累及小叶间隔比例小(12.5%比85.7%);有症状组26例(82.9%)病灶内小血管增粗,较无症状感染组的6例(50.0%)明显,差异有统计学意义(P<0.05)。结论COVID-19无症状感染者CT图像具有特征性,胸部CT检查对可疑人群排查具有非常重要的价值,有助于可疑患者的早发现、早隔离、早治疗。
Purpose To investigate the chest CT features of asymptomatic patients with COVID-19.Materials and Methods Sixteen patients with COVID-19 were enrolled in this study,all patients showed positive nucleic acid test,and without any clinically identifiable symptoms or signs,all CT features and clinical data were retrospectively analyzed.Twenty-eight patients with obvious clinical symptoms and positive nucleic acid test were included as controls,the range from the discovery of the lesion to the absorption of the lesion,the shape of the lesion,the characteristics of the lesion and features outside the lung of the two groups were compared.Results Compared with the symptomatic group,the asymptomatic infection group involved a smaller lung area,6 cases(50.0%)of which was single lung,a larger proportion of halo signs(66.7%vs.3.5%),and a smaller proportion of the lesion involving the lobular interval(12.5%vs.85.7%).26 cases(82.9%)showed the small blood vessels in the symptomatic group,which was significantly thicker than the asymptomatic group of 6 cases(50.0%),with statistical difference between the two groups(P<0.05).Conclusion The CT features of asymptomatic patients with COVID-19 are characteristic,and chest CT is very important for the investigation of suspicious people,it is helpful for early detection,early isolation and early treatment of suspicious patients.
