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 ...

In a PET scan, a machine detects the radiation that a radiotracer emits. A radiotracer consists of radioactive material tagged to a natural chemical, such as glucose. The radiologist injects this ...

A PET scan uses a radiotracer in the form of radioactive sugar. The body’s cells take in different amounts of the sugar, depending on how fast they are growing. Cancer cells grow quickly ...

Within cancer care, the radiotracer 18 F-FDG (fluorine-18-fluorodeoxyglucose) is used in PET/CT scans to identify increased glucose intake, a hallmark of cancer cells. And researchers have developed ...

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 ...

A more accurate way to scan for tuberculosis (TB) has been developed, using positron emission tomography (PET). The team has developed a new radiotracer, which is taken up by live TB bacteria in ...

The eight participants in the study received low doses (mean activity of 18.8 MBq) of radiotracer via intravenous infusion. The researchers then performed three total-body PET/CT scans: a 90-min ...

PET scans for cancer provide insight that can ... interferes with the images created by the scanner. You will receive a radiotracer either through an injection, inhalation (breathing it in ...

A PET scan is painless, with the possible exception of inserting the IV. You might feel a cold sensation in your arm when you get the radiotracer injection. Some people may have temporary ...

or carrying out a PET scan to look for signs of inflammation in the lung, using the common radiotracer FDG ([18 F]FDG). However, a sputum test can show a negative long before the disease has been ...

A more accurate way to scan for tuberculosis has been developed by researcher based in the U.K. and the U.S. using positron emission tomography (PET). The team has developed a new radiotracer ...
