Abstract

INTRODUCTION: The new Coronavirus (SARS-Cov-2) has hit the world in unpredictable ways. In addition to the more than 9.8 million confirmed cases, more than 494 thousand people have already died (27 June 2020). The virus directly affects the respiratory system, in addition to acting on the cardiovascular system. Its interference in several bodily functions has been reported, often changing local anatomy and morphology. In addition, the diagnosis of this disease has undergone constant updating and increasingly relies on radiological imaging tests to help and understand this new disease. Therefore, analyzes that provide knowledge about the relationship between images and the disease are extremely valid and deserve to be done. OBJECTIVE: To survey and describe the radiological findings obtained by imaging tests performed on patients with the SARS-CoV-2 virus. MATERIAL AND METHODS: This is a qualitative study, with a bibliographic reference, of the literature review type (n=14). The search was performed using the Health Sciences Descriptors (HCD): Radiology, Patients and Coronavirus Infections, in the Scielo, PubMed, SpringerLink, Bireme, Ebsco and Lilacs databases. The research was filtered by language (English, Portuguese and Spanish) and year of publication (2020). RESULTS: The studies were analyzed and it was found that when some patients clinically suspected of COVID-19 pneumonia underwent computed tomography, the results revealed that those affected had bilateral ground-glass opacity lung lesions, with no airway abnormalities, mediastinal lymphadenopathy and pleural effusion. Paving and senseless organization of the pneumonia pattern are seen at a later stage of the infection. Of the abnormalities, ground-glass opacities, uneven floor pattern and consolidation of surrounding halos are the most characteristic. Another study showed that faint interstitial parenchymal images, mainly located subpleurally and in the pulmonary bases, have been described. A radiograph without findings does not rule out pulmonary involvement that may be evident on computed tomography. Multiple opacities and bilateral multilobar consolidation images may be evident in critically ill patients with Adult Respiratory Distress Syndrome. CONCLUSION: The images obtained from the radiological exams of people affected by SARS-CoV-2 make it possible to collect important data to update management methods and, thus, clinical protocols, and to frequently improve patients' prognosis. In addition, more studies must be done in order to assist the process of continuous research and improvement, to build new parameters of knowledge and, thus, be able to offer a continuously better treatment.
