Ultra-high-field MRI reveals a venous-dominant microbleed phenotype in cerebral amyloid angiopathy: a comparative study versus 3 Tesla MRI.
7T MRI robustly improves CMB detection in CAA and provides higher inter-rater reliability for vCMB classification than 3T, but weak cross-scanner correlation and agreement for the vCMB-to-total ratio preclude interchangeability across field strengths.
