Positron Emission Tomography, PET is a nuclear medicine imaging test that helps the doctor to check cancer in your body. The scan uses a small amount of liquid radioactive tracer which is injected into the body and is used to diagnose a variety of diseases, including many types of cancers and brain and heart disease. The most common radioactive substance used for this purpose is FDG, fluorodeoxyglucose. These are either swallowed, inhaled or injected into the bloodstream and accumulates in the body where it gives off energy in the form of gamma rays. The tracer will get accumulated in areas of higher chemical activity and are detected by the PET scanners are bright spots these signals are converted into detailed images which shows how the tissue and organ is working.
