Correlation of Radiological Changes Detected 6–12 Months After Covid-19-Associated Pneumonia With the Area of Lung Tissue Lesions on Multispiral Computed Tomography of the Chest Organs

Background. Despite the end of the pandemic caused by the new coronavirus infection (COVID-19), many authors in their works draw attention to the persistence of clinical and radiological manifestations of this disease after recovery, within the so- called post-Covid syndrome [1, 2]. The search for predictors of the possible formation of fibrosis in lung tissue is of particular interest. This article presents the results of an analysis of the type and prevalence of radiological changes identified 6–12 months after COVID-19-associated pneumonia, with the area of lung tissue affected according to multispiral computed tomography (MSCT) of the chest in young patients. Purpose. To analyze the possible relationship of the types and frequency of detection of radiological changes detected 6–12 months after COVID-19-associated pneumonia with the affected area according to MSCT of the chest. Materials and methods. The study included 227 patients with an average age of 40.5±6.55 years who had pneumonia associated with COVID-19. High-resolution MSCT of the chest organs was performed using a 128-slice Philips device. Results. Statistically significant differences were revealed in the frequency of detection of post-inflammatory fibrosis between groups of patients depending on the initial area of damage to the lung tissue. Conclusion. In the group of patients with an initial lesion area of 50–75% (MSCT 3), post-inflammatory fibrosis in the lung tissue was more often recorded in comparison with the groups of patients with an initial lesion of 0–25% (MSCT 1) and 25–50% (MSCTCT 2).
