Amyloid PET Scans

Caption: PET scans reveal amyloid plaques, which appear as warm colors such as red, yellow and orange. On the left is a patient with Alzheimer's disease, and on the right is a person with no detectable amyloid deposits in the brain. The middle scan is of a normal person with no symptoms of cognitive problems, but with evident levels of amyloid plaque in the brain.
