Alzheimer’s disease (AD), also known as just Alzheimer’s, is a chronic neurodegenerative disease that usually starts slowly and gets worse over time . Advanced medical imaging with magnetic resonance imaging (MRI) can be used to help exclude other cerebral pathology or subtypes of dementia .
The primary role of MRI in the diagnosis of Alzheimer disease is the assessment of volume change in characteristic locations which can yield a diagnostic accuracy of up to 87%. Volumetric MRI can detect changes in the size of brain regions. Measuring those regions that atrophy during the progress of Alzheimer’s disease is showing promise as a diagnostic indicator. It may prove less expensive than other imaging methods currently under study.
