Question

Quizplus · Accepted Answer

Most PET tracers have a half-life between 2 minutes (120 seconds) to 110 minutes, which allows for enough time for the tracer to be administered, travel to the target organ or tissue, and be imaged before it decays. Tracers with shorter half-lives might not be able to reach the target in sufficient quantities, while those with longer half-lives might expose the patient to unnecessary radiation. Therefore, tracers with half-lives in the range of 2-110 minutes are the most suitable for PET imaging.
