Examples of Positron Emission Tomography (PET)

Imaging

PET images can show how different diseases causing memory loss and thinking problems affect the brain. These images show energy use in the brain on a color scale, shown at right.

The ¨hot¨ colors at the top of the scale reflect the highest activity, with green and blue regions showing low activity.

The top figure shows the brain as seen from the right. Even patients with only memory problems can have changes on PET scans. Patients who have both memory and other thinking problems show more changes on PET.

In Alzheimer's disease, these problems are primarily at the back of the brain. In a different type of dementia, called frontotemporal dementia or FTD, changes occur primarily in the front.

Alzheimer's Image Analysis Laboratory

Under the direction of Dr. Richard King, the Alzheimer's Image Analysis Laboratory (or AIAL) uses advanced neuroimaging analysis tools to study morphometric changes in the brain associated with neurodegenerative disease. To learn more about AIAL, visit them online at www.aial.utah.edu/.
