Abstract

Objective: This study aims to evaluate the computed tomography features of lung parenchyma, in patients who have recovered from Covid-19. Method: We enrolled 105 adult patients who recovered from Covid-19 for 3-6 months. All patients performed a non-contrast chest CT scans in Ha Noi Medical University Hospital between April 2022 and August 2022. The clinical symptoms and CT scan features were obtained. Results: One hundred five participants (mean age 52±13, range 25-70 years old; 50 men) were assessed. Breathlessness was reported in 20 of the 105 participants (19%), cough was reported in 85 (81%) and fever was reported in 5 patients (4,7%). CT scans in 105 participants revealed persistent abnormalities in 76 patients (72.3%), with ground-glass opacification in 61 patients (58%), brands in 31 patients (29.5%), consolidation in 10 patients (10%), bronchiectasis in 5 patients (5%). Most of the cases show lower zonal predominance (50 patients, 65.8%), and peripheral predominance (60 patients, 79%). Conclusion: CT abnormalities were common at 3-6 months after COVID-19. Ground-glass opacification is the most common features. Lower zonal and peripheral are predominance.
