Ultra-high-field MRI reveals a venous-dominant microbleed phenotype in cerebral amyloid angiopathy: a comparative study versus 3 Tesla MRI.
BACKGROUND AND PURPOSE Cerebral microbleeds (CMB) are core MRI markers of cerebral amyloid angiopathy (CAA). Ultra-high-field 7T MRI may improve CMB detection and visualization of venous-associated CMB (vCMB), but the extent to which this reflects additional lesion detection versus field-dependent phenotypic reclassifi...
