A positron emission tomography (PET) scan uses a tracer with low levels of radiation to find places in your body where cells are unusually active—which can mean they're cancerous. A PET scan can ...

When you get a PET scan, your doctor will give you a radioactive substance called a radiotracer (or just “tracer”). The PET scanner can see where this tracer goes in your body. If it builds up ...

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 ...

PET stands for positron emission tomography. A PET scan uses a mildly radioactive liquid called a radioactive tracer. It shows areas of your body where cells are more active than normal. It's used to ...

Biopsies are the only way to confirm NHL. PET is a scan that uses a tracer to show tumor activity. Research published in 2017 indicates that lymphoma cells are particularly responsive to a tracer ...

A small number of prostate cancers do not produce this protein. A PET scan uses what’s called a radiotracer, or simply a tracer, which is a small amount of radioactive material. It is injected ...

Dual isotope imaging Overview of multiplexed PET using a pure positron emitter and a positron–gamma emitting radionuclide. (Courtesy: E C Pratt et al Nat. Biomed. Eng 10.1038/s41551-023-01060-y) ...

A positron emission tomography or PET scan often relies on injecting a small amount of radioactive glucose, called a tracer, into the bloodstream. The scanner creates a picture based on where the ...

A new PET scan reliably detects benign tumors in the pancreas, according to research led by Radboud university medical center. Current scans often fail to detect these insulinomas, even though they ...

PET beta-amyloid imaging, or amyloid PET scans, can detect amyloid plaques by injecting a radioactive tracer into the body that binds to amyloid plaques in the brain. The PET scan then produces ...

In this process a tracer like fluorodeoxyglucose is injected in the body that can be traced with the help of the tomography machine. Drinking coffee before having a PET scan will interfere with ...
