Application of multislice spiral computed tomography in the follow-up of patients with various clinical types of COVID-19

摘要

In order to provide a better understanding of dynamic outcome characteristics of COVID-19, the data of 95 patients with pathologically confirmed COVID-19 in the People's Hospital of Baoding, the Fourth People's Hospital of Nanning, and the Beijing You'an Hospital of Capital Medical University between January 20, 2020 to February 20, 2020, were retrospectively reviewed. All patients received MSCT scans during their hospitalization with intervals of seven days, and underwent a re-examination as their final follow-up visit on the 14th to 30th day after discharge. Chest CT scans were performed on all patients. Patients with COVID-19 have been categorized as mild (8 patients), moderate (63 patients), severe/critical (24 patients) according to their radiographic and clinical features. 1 The focus of the assessment was on the radiographicfindings in the moderate group and the severe/critical group during the peak stage (the most severe disease in the lungs), early outcome stage (first improvement of the lesion), advanced outcome stage (7e14 days after the peak stage), and recovery stage (14e30 days after discharge). The location and range of lesions, lesion characteristics and pleural conditions, and dynamic lesion changes were all observed.
