Using 7T MRI to Evaluate COVID‐19 and Brain

SARS‐CoV‐2 causes neurological, psychiatric and neurocognitive deficits in a large proportion of patients via direct or indirect viral invasion, systemic or intracranial inflammation, micro‐ or macrovascular pathologies, and hypoxic or systemic metabolic complications. The insult to brain function during the acute phase of COVID‐19 may accelerate neurodegenerative process and potentially increase the risk of Alzheimer’s Disease or Related Dementias. Ultrahigh Field (7T) MRI has an enhanced sensitivity and spatial resolution over and above clinical 3T MRI, allowing detection of small changes in brain sub‐structures and integrity.
