The long-term pulmonary sequelae in COVID-19 patients remain a crucial area of investigation. This study aims to evaluate the resolution of pulmonary abnormalities in COVID-19 survivors through serial CT scans. Methods: An observational study was conducted on 80 COVID-19 patients, with CT scans performed during hospitalization and at two follow-up intervals. Ground glass opacities, consolidation, interstitial septal thickening, and fibrous bands were among the evaluated radiological findings. Results: At baseline, ground glass opacities were present in all patients (100%), with a significant resolution by the second follow-up (complete resolution in 51.2%). Consolidation was observed in 78.8% of patients initially, with 84.1% showing complete resolution at the second follow-up. Interstitial septal thickening and fibrous bands also showed considerable resolution over time. A significant correlation was found between higher CRP levels and increased CTSI scores (p=0.0001). Conclusion: The study demonstrates a significant resolution of initial pulmonary abnormalities in COVID-19 patients over time. The findings highlight the potential for lung recovery post-COVID-19, while also emphasizing the importance of monitoring for long-term sequelae, especially in patients with severe initial presentations.
