WebIn general, PET scans may be used to evaluate organs and/or tissues for the presence of disease or other conditions. PET may also be used to evaluate the function of organs, such as the heart or brain. The most common use of PET is in the detection of cancer and the evaluation of cancer treatment. More specific reasons for PET scans include ... WebThe Process of Annihilation. When a positron is emitted from a tracer in the body, it travels less than a millimetre before it collides with an electron. The positron and the electron will annihilate, and their mass becomes pure energy in the form of two gamma rays which move apart in opposite directions. Annihilation doesn’t just happen with ...
