Positron Emission Tomography
People also ask
How does a PET scan detect hypermetabolic activity?
A PET scan (positron emission tomography) works to identify areas of hypermetabolic activity anywhere in the body. A radioactive substance is given to the patient and this attaches to glucose, which is attracted to cells that are hypermetabolic.
What is a PET scan and what does it show?
A positron emission tomography (PET) scan is an imaging test that shows the metabolic activity (energy usage) of your body.
What does metabolic activity mean on pet?
Subsequently, question is, what does metabolic activity mean? Metabolic activity, as defined by the uptake of 18F-fluorodeoxyglucose (FDG) on positron emission tomography (PET), takes advantage of the physiologic preferential use of anaerobic glycolysis over oxidative phosphorylation used by malignant cells for their energetic needs.
How long does a PET scan take to produce?
During a positron emission tomography (PET) scan, you lie on a narrow table that slides into a doughnut-shaped hole. The scanner takes about 30 minutes to produce detailed images of metabolic activity in your tissues and organs.
