Positron emission tomography (PET) makes use of little amounts of radioactive components referred to as radiotracers, a special camera and a computer to assist evaluate your organ and tissue functions. Positron emission tomography, also called PET imaging or a PET scan, is a sort of nuclear medicine imaging. Generally, you will be asked not to consume anything for a number of hours ahead of a entire physique PET/CT scan given that consuming may alter the distribution of the PET tracer in your body and can lead to a suboptimal scan.
