Infection Coronavirus, Radiography, Computed Tomography., COVID-19Abstract
In late 2019 a new coronavirus called SARS-CoV-2 appeared in Wuhan, China and was responsible for a pandemic with unprecedented repercussions. However, it is known that about 20 years ago, in 2002, the country had an epidemic of another coronavirus, the SARS-CoV, and its carriers presented a clinical picture very similar to those infected by the new virus. In addition to the clinic, the radiological presentation, in general, is also similar. Thus, the present study aims to analyze and compare the radiological changes present in both infections, as well as the scientific production about these findings, through a literature review. The research for theoretical framework occurred in August 2020 through the databases of Scielo, Medscape and PubMed, in addition to medical protocols. After applying the inclusion and exclusion criteria, twenty-one articles and six protocols were selected that met the research’s objective. The radiological changes of SARS-CoV and SARS-CoV-2 are, in general, similar, although there are some differences in relation to virulence and the degree of progression of pulmonary involvement. As for the best imaging method, radiography can stand out as a cheaper and more accessible tool, taking into account health services’s overload in a worldwide pandemic context.
