While the presence of beta-amyloid plaques in the brain may be a hallmark of Alzheimer's disease, giving patients an amyloid PET scan is not an effective method for measuring their cognitive function, ...

Scanning a patient's brain metabolism with positron-emission tomography (PET) can improve a doctor's ability to forecast the patient's future cognitive functions by up to 30 percent, a new ...

How and Why a PET Scan Is Done and Possible Side Effects ...

Tau proteins play an important role in our normal brain function, mainly by helping to stabilize neurons in the brain. But in Alzheimer’s disease, tau proteins can misfold and tangle inside neurons.

At first glance, it might appear that better access to so-called amyloid-PET scans could compensate for some of the racial inequities in Alzheimer’s disease, as Linda Goler Blount called for in a ...

A novel technique that reduces image degradation caused by respiratory motion during a PET scan was developed through a recent study. PET scanning is routinely used to detect cancer and heart ...

A positron emission tomography (PET) scan is a diagnostic tool that examines body tissue functioning, such as blood flow, oxygen use, and sugar metabolism, to help doctors diagnose and treat disease.

Positron emission tomography (PET) scans can detect cancer earlier than other imaging tests. But some types of cancer are harder to detect on a PET scan. In particular, they may miss cancers that ...
