7T MRI scans provide a high-res look at how migraines affect the brain

Ultra-high-res MRI Reveals Migraine Brain Changes
(A) Cerebral microbleeds (CMB) visualized as round, dark lesions (arrow) on SWI sequence in the left temporal lobe in a migraine case with aura. (B) Asymmetry in the appearance of the cortical vessels is more prominent on the left side (arrow) ipsilateral to the CMB. Images courtesy of RSNA.

In a new analysis, scheduled to be presented at RSNA 2022 in Chicago, researchers have identified enlarged perivascular spaces in the brains of migraine patients. This may be suggestive of waste clearance issues in the central nervous system.
