| Alzheimer’s
disease:
PET scans show a very consistent diagnostic pattern
for Alzheimer’s disease, where certain regions
of the brain have decreased metabolism early in
the disease (see arrows). In fact, this pattern
often can be recognized several years before a
physician is able to confirm the diagnosis and
is also used to differentiate Alzheimer’s
from other confounding types of dementia or depression..

Parkinson disease:
PET images of the brain can accurately identify
Parkinson’s
|
| Epilepsy:
PET images of the brain identify regions of reduced
glucose metabolism, pinpointing the epileptogenic
tissue.
Surgical techniques are now available to successfully
remove the tissue, leading to a definitive cure
of the seizure disorder in 80% of these children.
