Abstract

Purpose: To analyze imaging characteristics of lung injury on multi-slice computed tomography in patients with post-COVID-19 at Phu Tho General Hospital in 2022. Results: The study was performed on 45 patients (46.7% male, 53.3% female),  with an average age of 70.44 ± 13.19 years old. The pulmonary lesions seen on the CT scan were interstitial thickening 66.7%), ground glass opacity (48.9%), consolidation (40%), crazy-paving pattern (15.6%), bronchiectasis (40%), alveolar dilatation (24.4%), subpleural bands (37.8%), honeycombing (13.3%), reversible halo/halo sign (13.3%). The average CT score of patients in the study group was 6.80 ± 5.48 points The lowest score is 0 points, the highest is 21 points. The age threshold at risk for post-COVID-19 lung damage was 70.5 years with a sensitivity of 73.3% and a specificity of 60%. Conclusions: High-resolution multi-slice computed tomography should be performed in all patients with post-COVID-19 persistent symptoms. Common lesions seen on CT scans are interstitial thickening, and ground glass opacity. There are also fibrotic-like changes suggestive of post-COVID-19 pulmonary fibrosis.
