Abstract:
Objective:To analyze the clinical features and imaging findings of chest computed tomography (CT) of patients with corona virus disease 2019 (COVID-19), and to provide imaging guidance for early diagnosis and clinical treatment.Methods:A total of 74 patients diagnosed with positive nucleic acid test of nasopharyngeal swab were retrospectively collected from January 23 to February 22, 2020 in the inpatient department of Rui′an People′s Hospital. Their clinical features were analyzed in combination with CT image characteristics.Results:Of the 74 patients, 62 (83.8%) had fever, 59 had abnormalities in CT examinations and 15 patients had no imaging abnormalities. The average interval from onset to CT examination was 4.6 days. Among 59 patients, 58 cases (98.3%) were mainly peripherally distributed, 53 cases (91.4%) had multiple lesions and five cases (8.6%) had single nodules. The main manifestation was ground glass opacities (45 cases, 76.3%). The lesions were mainly distributed in the middle and lower lobe of the lungs, accounting for 76.3% (45 cases). Air bronchogram was shown in 21 cases (35.6%), and reversed halo sign was shown in 10 cases (16.9%). Other rare abnormalities were small cavities in three cases (5.1%), tree-in-bud pattern in one case (1.7%). Intrathoracic lymph node enlargement was found in two cases (3.4%) by re-examination.Conclusion:The CT examination characteristics of COVID-19 patients could play an important role for early diagnosis and follow-up.
