Alzheimer's disease is a neurodegenerative disorder characterized by a decline in memory, cognitive function and cerebrovascular dysfunction. In this study we used a presenilin-1/amyloid precursor protein (PS/APP) transgenic mouse model of AD to assess perfusion and diffusion MRI methods that could be useful in detecting and studying AD. We utilized a recently developed cardiac spin labeling (CSL) technique to image basal cerebral blood flow and hypoxia-induced blood oxygen level dependent (BOLD) and CBF changes in PS/APP mice. Additionally, diffusion tensor imaging was performed to image apparent diffusion coefficient and fractional anisotropy in PS/APP and control mice.
