CT features and analysis of 17 cases of COVID-19

Objective: To investigate the CT features of Corona Virus Disease 2019 (COVID-19) and evaluate the CT value in the diagnosis. Methods: CT images of 17 confirmed COVID-19 patients from 3 hospitals were retrospectively analyzed. The characteristic manifestations of the disease on CT imaging were analyzed, and the characteristics of single/multiple lesions, affected sites, and distribution of lesions were summarized. Results: All patients presented abnormal CT findings with a single exception, a total of 111 lesions were identified in the 16 patients. The typical CT findings included ground-glass opacity (62/111, 55.9%), consolidation with ground glass opacity (16/111, 14.4%), consolidation (18/111, 16.2%) and crazy-paving pattern (15/111, 13.5%). The lesions were mostly distributed in the peripheral zone of lungs (93/111, 83.8%). No case presented pleural effusion and lymphadenopathy of the mediastina. Conclusion: The CT imaging of COVID-19 has certain characteristic manifestations, and CT plays an important role in the detection and definite diagnosis of lesions. (authors)
