Dementia Of The Alzheimer Type
Functional imaging methods used in research on aging, mild cognitive impairment, and dementia of the Alzheimer type include single-photon emission computed tomography (SPECT), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI). Positron emission tomography and single-photon emission computed tomography use radioisotope tracers to detect brain metabolism or blood flow. Functional magnetic…
