| خلاصه مقاله | Introduction:
Coronavirus in COVID-19 not only involves the human respiratory system but can also spread from the respiratory system to the central nervous system and causes brain damages and neurological manifestations. Several studies and case reports have reported the findings of the brain MRI in COVID-19 patients using different MRI techniques. This study aimed to review the brain MRI techniques and clinical findings in patients with COVID-19.
Methods:
Literatures search was carried out using scientific databases including; Scopus, PubMed, Web of Science, and Google Scholar. The articles describing brain MRI techniques and clinical findings in patients with COVID-19 were found and reviewed.
Results:
The most applied MRI pulse sequences and techniques for brain MRI in COVID-19 patients included; pre and post-contrast T1-weighted spin-echo, diffusion weighted imaging (DWI), susceptibility-weighted imaging (SWI), T2-weighted gradient-echo, and post contrast fluid-attenuated inversion recovery (FLAIR). Different findings of the brain MRI in COVID-19 patients were reported, such as; acute ischemic infarcts, intracranial hemorrhage, parenchymal abnormality attributed to posterior reversible encephalopathy syndrome, and leukoencephalopathy.
Conclusion:
Using appropriate MRI techniques better detects the brain damages caused by the coronavirus. MRI findings of the brain may help radiologists and neurologists to provide potential insight in the case of COVID-19 brain damages. |
