The image on the left is a PET scan of a normal brain. The image on the right is heavily blackened throughout the cerebral cortex due to the the presence of amyloid plaques. Amyloid is found in the brains of patients with dementia due to Alzheimer’s disease

In research studies, scientists regularly use positron emission tomography (PET) scans to detect signs of Alzheimer's disease. Now, Washington University physicians at Barnes-Jewish Hospital are the first in Missouri to offer a new type of PET scan for patients with memory disorders and other forms of cognitive impairment who are not involved in research studies.
