C)fragments
D)nucleons

Question

Quizplus · Accepted Answer

PET scans use radioactive isotopes that emit positrons as they decay. These positrons interact with electrons in the body, resulting in the emission of gamma rays that can be detected by the PET scanner to produce an image. Fluorodeoxyglucose (FDG) is a commonly used radioactive isotope in PET scans.
