Positron emission tomography (PET) utilizes modest amounts of radioactive supplies called radiotracers, a particular camera and a laptop to assist evaluate your organ and tissue functions. It can take a number of hours to days for the radiotracer to accumulate in the physique portion of interest and imaging could take up to a number of hours to execute, although in some cases, newer gear is obtainable that can substantially shorten the procedure time.
