title: Neuroimaging and dementia.
abstract: The tremendous increase in dementia has created a need for improved diagnostic techniques, and each of the newly established brain imaging techniques has been applied to this problem. Several, particularly computerized tomography (CT), magnetic resonance imaging (MRI), and isotope emission tomography, have proved valuable. Each procedure has strengths--specific disorders that can be diagnosed--and weaknesses--types of dementia that cannot be demonstrated.
