CT Scan Findings in Patients with COVID-19: A Comparison Study Between Vaccinated and Non-vaccinated

Abstract

Background: Computed tomography (CT) scan findings of patients with and without vaccination can enhance the current understanding of the effectiveness of vaccines in preventing pneumonia and other complications of COVID-19 in the lungs. Objectives: This study aimed to compare chest CT scan findings in vaccinated and unvaccinated patients with COVID-19. Methods: This study included patients aged 20 to 50 years diagnosed via polymerase chain reaction (PCR) at university hospitals in Zahedan. Patients were selected based on predefined inclusion criteria, with no exclusion criteria applied. Results: A total of 189 patients with an average age of 35.71 ± 6.56 years were included in the study, of whom 109 patients (57.7%) were female and the rest were male. The most common finding in the CT scans was ground-glass opacity (GGO), observed in 146 patients (77.2%). Conclusions: Based on the results obtained in the present study, vaccination against COVID-19 reduces the severity of the radiological manifestations of this disease.
