MRI Reveals Significant Brain Abnormalities Post-COVID (IMAGE) Radiological Society of North America Caption Group analysis on susceptibility-weighted imaging exhibiting higher susceptibility-weighted imaging values in the COVID group when compared to healthy controls. Three significant clusters were found primarily in the white matter regions of the pre-frontal cortex and in the brainstem. The clusters (a) and (b) are observed bilaterally in the cerebral white matter near the orbitofrontal gyrus, whereas (c) lies in the midbrain region. Credit RSNA and Sapna S.
