Positron Emission Tomography How It Works. Posted March 23 2016 anosh01. In PET scanning the engine detects radiation emitted by the radiotracer. These substances are injected into the body and are usually tagged with a radioactive atom such as Carbon-11 Fluorine-18 Oxygen-15 or Nitrogen-13 that has a short decay time. The scan captures images of the activity of the brain after radioactive.
PET offers quantitative analyses allowing relative changes over time to be monitored as a disease process evolves or in response to a specific stimulus. Positron emission tomography PET is a technique that measures physiological function by looking at blood flow metabolism neurotransmitters and radiolabelled drugs. Because positron emission tomography is a mouthful radiologists call it a PET scan for short. Positron emission tomography PET uses small amounts of radioactive materials called radiotracers or radiopharmaceuticals a special camera and a computer to evaluate organ and tissue functions. The scan captures images of the activity of the brain after radioactive. A brain positron emission tomography PET scan is an imaging test that allows doctors to see how your brain is functioning.
PET is actually a combination of nuclear medicine and biochemical analysis.

Doctors often use the diagnostic exam often to detect cancer and measure the effects of cancer. Positron emission tomography PET scans produce detailed 3-dimensional images of the inside of the body. This post aims to explain what positron emission tomography PET is and how it works.
