Research Abstract:

Dr. Benzinger`s research focuses on translating advanced neuromagnetic resonance imaging techniques from small animal research in the Department of Radiology, to translational research in the Center for Clinical Imaging Research (CCIR), and into clinical practice. In particular, her current research focuses on using directional diffusivity measurements derived from diffusion tensor imaging (DTI) to measure axonal and myelin damage in pediatric and adult demyelination, dysmyelinating diseases, in traumatic brain injury (TBI), and as a function of aging. Diseases under study in Dr. Benzinger`s laboratory include multiple sclerosis (MS), acute disseminated encephalomyelitis (ADEM), adrenoleukodystrophy, Krabbe`s disease, Pelizaeus-Merzbacher`s disease, and head trauma. In addition, Dr. Benzinger combines advanced neuromagnetic resonance techniques, such as DTI and spectroscopy, and positron emission tomography (PET) to study interactions between normal aging, Alzherimer`s disease, depression, and delirium in older adults.
