Abstract

Objectives: Lung-CT-scan imaging is known as important diagnostic technique for evaluation of the effectiveness and infectious involvement of the lungs. In this study, we evaluated and analyzed lung CT images in patients with Coronavirus Disease 2019 (COVID-19) and its relationship with some important clinical and laboratory factors as well as the patient's condition in the worst disease conditions. Methods: In this retrospective descriptive-analytical study, 375 patients with complete information have been considered. Among these patients, CT scans of patients' lungs was carefully reevaluated. Other radiologist reviewed the images and recorded the final score of the patients' lung involvement. Results: Data showed that lung and cardiac involvement have high prevalence among studies patients. Among demographic variables, there was significant relationship between age and recovery. Evaluating the relationship of recovery with CT variables showed that CT score, bilateral lung involvement, and Crazy paving had significant effect on recovery rate. Conclusion: According to this study, evaluation of CT variables can be used as potent factors for evaluation of disease status and design of suitable treatment strategy.
