Stroke or cerebrovascular attack (CVA) is the first cause of disability and the third cause of death in Argentina and in the world. The etiology of strokes is mostly ischemic (more than 80% of cases), with the most frequent causes being lacunar-ty-pe ischemic lesions of small vessels and thromboembolic lesions due to atherosclerosis of large arteries or cardioembolism. The sequences used in our study protocol include DWI, FLAIR, angio-RM 3D-TOF, SWI, and FSE-T1 (approximate scan time of 13 minutes). Different findings can be observed in each of these sequences that are indicative to determine the underlying etiology and estimate the time of evolution of the lesion. Currently, mechanical thrombectomy has become the treatment of choice in selected patients with acute ischemic stroke. Hemorrhagic transformation is the most feared complication after intra-arterial reperfusion therapy. The diffusion magnetic resonance technique is more sensitive for detecting ischemic lesions, allows one to suspect the etiology based on the lesion pattern, and provides valuable information for the selection of patients who are candidates for arterial reperfusion.

The current SARS-CoV-2 pandemic has changed the way we work and interact. It was notified in Wuhan, Hubei province, China, in December 2019. There had been two previous major outbreaks of Coronavirus: SARS in 2002-2003 and MERS in 2012. This article aims to be a brief review of some aspects of the COVID-19 infection from the pathophysiological aspects, imaging findings, as well as the main indications for the imaging, although these will always be individualized. We cannot ignore the possibility that some of these patients may present evolution to pulmonary fibrosis. Finally, we will mention some recommendations to protect ourselves in our workplace.
