To investigate the CT findings of patients with different clinical types of coronavirus disease 2019 (COVID-19).
A total of 67 patients diagnosed as COVID-19 by nucleic acid testing were collected and divided into 4 groups according to the clinical stages based on . The CT imaging characteristics were analyzed among patients with different clinical types.
Among 67 patients, 3(4.5%) were mild, 35 (52.2%) were moderate, 22 (32.8%) were severe, and 7(10.4%) were critical ill. No significant abnormality in chest CT imaging in mild patients. The 35 cases of moderate type included 3 (8.6%) single lesions, the 22 cases of severe cases included 1 (4.5%) single lesion and the rest cases were with multiple lesions. CT images of moderate patients were mainly manifested by solid plaque shadow and halo sign (18/35, 51.4%); while fibrous strip shadow with ground glass shadow was more frequent in severe cases (7/22, 31.8%). Consolidation shadow as the main lesion was observed in 7 cases, and all of them were severe or critical ill patients.
CT images of patients with different clinical types of COVID-19 have characteristic manifestations, and solid shadow may predict severe and critical illness.
探讨2019冠状病毒病（COVID-19）不同临床类型患者的CT表现。
收集67例经核酸检测确诊为COVID-19的患者，根据临床分期分为4组。分析不同临床类型患者的CT影像特征。
67例患者中，轻症3例（4.5%），普通型35例（52.2%），重型22例（32.8%），危重型7例（10.4%）。轻症患者胸部CT影像无明显异常。普通型35例中单发病灶3例（8.6%），重型22例中单发病灶1例（4.5%），其余为多发病灶。普通型患者CT图像主要表现为实性斑片状影及晕征（18/35，51.4%）；重型患者以纤维条索影伴磨玻璃影较为多见（7/22，31.8%）。7例以实变影为主病灶的患者均为重型或危重型患者。
COVID-19不同临床类型患者的CT图像有特征性表现，实性影可能提示重型及危重型病情。
