  2. PET radiotracer - Wikipedia

    en.wikipedia.org/wiki/PET_radiotracer

    PET radiotracer is a type of radioligand that is used for the diagnostic purposes via positron emission tomography imaging technique. [1] [2]

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 These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope.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

  4. 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.

  6. Brain positron emission tomography - Wikipedia

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

    Detectors in the PET scanner detect the radioactivity as the compound charges in various regions of the brain. A computer uses the data gathered by the detectors to create multi-dimensional (normally 3-dimensional volumetric or 4-dimensional time-varying) images that show the distribution of the radiotracer in the brain following the time.

  7. 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.

    Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...

  9. Radioactive tracer - Wikipedia

    en.wikipedia.org/wiki/Radioactive_tracer

    A radioactive tracer, radiotracer, or radioactive label is a synthetic derivative of a natural compound in which one or more atoms have been replaced by a radionuclide (a radioactive atom). By virtue of its radioactive decay , it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from ...
