  • Clinical and CT findings of coronavirus disease 2019

    ObjectiveTo investigate the clinical and CT findings in patients with coronavirus disease 2019 (COVID-19).MethodsThe epidemiological data and clinical manifestations of 83 COVID-19 patients admitted to Chongqing Public Health Medical Center from January 24, 2020 to February 4, 2020 were analyzed retrospectively. According to the clinical classification, they were divided into four groups: mild group 8 patients, common group 62 patients, severe group 10 patients, and critically severe group 3 patients. The CT characteristics and their relationship with clinical classification were analyzed.ResultsThe average age of 70 mild patients was (43.7±15.0) years, 13 severe patients was (57.4±11.8) years. The average age of mild patients was lower than that of severe patients (Z=–3.185, P=0.001). The average course of mild disease was (5.5±4.2) days, lower than that of severe disease (11.8±5.0) days (Z=–3.978, P=0.000). The clinical manifestations were fever in 72 patients, cough in 60 patients, expectoration in 34 patients, asthenia in 25 patients and shortness of breath in 19 patients. Basic diseases were complicated in 16 patients. CT findings: Both lung lobes were affected in 70 patients (93.3%), pure right lung lobe was affected in 3 patients (4.0%), pure left lung lobe was affected in 2 patients (2.7%), and there was no focus in 8 patients. The total number of affected lung segments was 203 in severe type, with an average of 15.6±5.4 and 530 in the common type, with an average of 9.6±5.3. The number of the severe type was more than that in the common type (Z=–3.456, P=0.001). The focus was mainly in the posterior part, 62 in the dorsal and 65 in the posterior basal segments, 41 in the anterior part of the upper lobe, and less in the common type (P<0.05). The main lesions were ground-glass opacities in 74 patients, patchy shadow in 72 patients, piece shadow in 46 patients, strip shadows in 51 patients and consolidation in 34 patients. Among them, the common CT showed patchy shadow in 34 patients (54.8%), less than severe patients in 12 patients (92.3%) (χ2=4.880, P=0.027). There was no significant difference between the mild CT and the severe patients (P>0.05).ConclusionsThere are some radiographic characteristics in COVID-19. Chest CT is helpful for the diagnosis and the judgement of the disease.
