COVID 19: Radiological methods and characteristics of radiological findings

Abstract

COVID - 19 is a 21st-century pandemic. Coronavirus 2 (SARS-CoV-2) causes coronavirus disease - COVID-19 (Corona Virus Disease-19), zoonose. The virus was previously known as the 2019 novel coronavirus. A non-specific and most common clinical and radiological finding is pneumonia, which was called novel coronavirus-infected pneumonia (NCIP) duo to its previous virus name. Pneumonia is bilateral, peripheral localization, and basal distribution. So far, there is no specific treatment or vaccine to prevent COVID-19; all measures consist of supportive therapy. The clinical presentation varies in severity from asymptomatic to mild form of the disease, over severe forms to fatal outcomes. Depending on the stage of COVID-19, the findings obtained using radiological methods also depend. About half of the patients have a normal CT scan within the first two days of the onset of the disease. However, the occurrence of pathological findings reaches its maximum between days 9 and 13. At first, the zones of "ground glass" opacification are present, followed by the discovery of "crazy paving" , and then the development of consolidation. With the improvement of the disease, fibrosis zones occur, and the changes recede one month and beyond. Echosonography has an important place in the monitoring and management of severe patients in intensive care units, and especially in lung conditions.
