  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. Different tracers are used for various imaging ...

  3. PET-CT - Wikipedia

    en.wikipedia.org/wiki/PET-CT

    Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image.

  4. PET radiotracer - Wikipedia

    en.wikipedia.org/wiki/PET_radiotracer

    A fully automated radiosynthesis interface of PET-radiotracers. 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 , which is introduced into the body on a biologically active molecule. [3]

  5. List of PET radiotracers - Wikipedia

    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 These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope.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

    The MGH Gordon Center also operates the PET Core, an MGH research service facility that synthesizes radiotracers and provides positron emission tomography imaging services for investigators. [ 2 ] Created in 2015 with an endowment from the Bernard and Sophia Gordon Foundation, [ 3 ] the Gordon Center is a direct continuation of MGH's Division ...

  8. 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.

  9. Michael E. Phelps - Wikipedia

    en.wikipedia.org/wiki/Michael_E._Phelps

    Phelps' initial work dealt with the application of basic nuclear physics, chemistry, and mathematics to biomedical imaging. He combined a number of original insights in developing PET: First, he recognized that positron decay provides the opportunity for a unique coincidence detection system, with opposing detectors.
