A potential underlying mechanism for dementia through Alzheimers Disease (AD) could be that microscopic vascular abnormalities cause leakage of the blood brain barrier prior to neuronal damage. The primary aim of this pilot study is to assess the feasibility of detecting this damage in terms of the pharmacokinetic parameters fractional blood volume (vb) and leakage (Ki), in brains suffering from (preclinical) AD with a dual-temporal resolution DCE-MRI sequence. Also, the minimally required scan duration was investigated.
