Tau proteins play an important role in Alzheimer's disease. Tau helps to stabilize neurons in the brain, but in Alzheimer's disease, tau proteins can misfold and tangle inside neurons. These tangles ...

Researchers use AI and postmortem tissue to reveal that tau PET scans are often influenced by iron and neuroinflammation rather than tau tangles alone.

A heart PET scan is a noninvasive imaging test that uses a small amount of radiation. It helps doctors understand how the heart functions and whether it is healthy. Cardiac or heart PET scans create ...

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 ...

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.

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.
