Projects

Projects in Mayo Clinic's Aging and Dementia Imaging Research (ADIR) Lab focus on neuroimaging to diagnose Alzheimer's disease and related dementias before symptoms occur to treat the disease more effectively.

The ADIR lab uses modern brain-imaging modalities including amyloid positron emission tomography (PET), fluorodeoxyglucose (FDG) PET, tau PET, anatomic magnetic resonance imaging (MRI), diffusion imaging, perfusion imaging, task-free functional MRI and magnetic resonance spectroscopy, along with clinical, psychometric, genetic and neuropathologic information.
