Gao, Lulu; Zhang, Jianjun

From 20 January 2020 to 2 February 2020, 6 patients diagnosed with COVID-19 in our hospital were recruited, including 1 male and 5 females (average age 40±10 years) ( Table 1) . All patients underwent HRCT within 2 days after the onset of symptoms. All 6 patients had visited Wuhan or had contact with a confirmed COVID-19 patient. The clinical manifestations of these patients included fever, cough, sore throat, and fatigue. All patients were positive for 2019 novel coronavirus nucleic acid via laboratory testing of respiratory secretions obtained by bronchoalveolar lavage, endotracheal aspirate, nasopharyngeal swab, or oropharyngeal swab. HRCT images were acquired using a GE scanner (GE Medical Systems Optima CT540) with slice thickness of 1.25 mm. The images were transmitted to the workstation and viewed in the PACS system. CT images were evaluated by 2 experienced radiologists. In case of disagreement, a third senior radiologist offered an opinion and made the decision. Imaging features were evaluated in the following patterns: Data are presented as numbers (%) or median (IQR).
