The article focuses on positron-emission tomography which displays the concentration of radioactively labeled substances in the living body with improved clarity. Positron-emission tomography (PET) is a technique that combines biochemical assessment of pathology achieved by nuclear medicine with the precise localization achieved by computerized image reconstruction. In PET, a chemical compound with the desired biological activity is labeled with a radioactive isotope that decays by emitting a positron.
