Abstract

Background: The in vivo diagnosis of cerebral amyloid angiopathy (CAA) is inferred from clinical and structural imaging features. C-Pittsburgh compound B (PIB) is a PET ligand that binds to β-amyloid in extracellular plaques and vessel walls. We hypothesized that patients with a clinical diagnosis of CAA-related hemorrhage (CAAH) have increased C-PIB uptake and that the pattern differs from Alzheimer disease (AD). Methodology: Patients with CAAH based on established clinical criteria were studied using C-PIB PET and were compared with age-matched controls and patients with AD. Distribution volume ratio (DVR) parametric maps were created using the cerebellar cortex as a reference region. Resu..
