A Quick Look at PET Scans

Imaging centers in San Antonio can perform PET scans to detect cancer, and monitor its progression or treatment. This medical imaging test can also allow doctors to monitor blood flow to the heart. When you watch this video, you’ll see a simple animation that explains the technology behind PET scans.

PET scans, or positron emission tomography tests, involve the introduction of radioactive tracers into the body. These tracers bind to certain sugars or proteins. The radioactive isotope produces positrons. As these positrons interact with electrons, both of these particles are destroyed and 2 photons are released. The PET scanner detects the photons and uses advanced software to create 3D images with this information.
