Features of computed tomography in diagnostics COVID-19

COVID-19 (Coronavirus disease-19) is an acute infectious disease caused by the SARS-CoV-2 coronavirus. First identified in Wuhan (China) in December 2019, COVID-19 has spread widely outside of China. High contagiousness, severe clinical course of the disease and a high risk of developing complications leading to death - all this determines COVID-19 as the most pressing problem of the global medical community. Today, not only clinical, laboratory, but also radiodiagnosis of manifestations of pulmonary pathology in COVID-19 deserves special attention. Among the main CT signs of COVID-19 viral pneumonia, the presence of polygonal ground-glass infiltrates is noted. In the course of our study, it was revealed that one of the reasons for the incorrect interpretation of computed tomography images of patients with COVID-19 associated lung lesions was the failure to comply with the research methodology. False-positive scan results based on the results of computed tomography on the presence of ground glass changes in the lung parenchyma may be associated with the impossibility of holding the breath during the study (the patients serious condition and violation of the technique).
