  2. Positron emission tomography - Wikipedia

    en.wikipedia.org/wiki/Positron_emission_tomography

    Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.

    In PET imaging, [18 F]FDG is primarily used for imaging tumors in oncology, where a static [18 F]FDG PET scan is performed and the tumor [18 F]FDG uptake is analyzed in terms of Standardized Uptake Value (SUV). FDG PET/CT can be used for the assessment of glucose metabolism in the heart and the brain.

    en.wikipedia.org/wiki/List_of_PET_radiotracers

    This is a list of positron emission tomography (PET) radiotracers. These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope. Cardiology

  5. PET radiotracer - Wikipedia

    en.wikipedia.org/wiki/PET_radiotracer

    PET is a functional imaging technique that produces a three-dimensional image of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron -emitting radionuclide ( tracer ), which is introduced into the body on a biologically active molecule.

  6. Brain positron emission tomography - Wikipedia

    en.wikipedia.org/wiki/Brain_positron_emission...

    Brain positron emission tomography is a form of positron emission tomography (PET) that is used to measure brain metabolism and the distribution of exogenous radiolabeled chemical agents throughout the brain. PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream.

    The most widely used is 67 Ga for gallium scans. 67 Ga is used because, like 99m Tc, it is a gamma-ray emitter and various ligands can be attached to the Ga 3+ ion, forming a coordination complex which may have selective affinity for particular sites in the human body.
