  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.

    en.wikipedia.org/wiki/Flutemetamol_(18F)

    Average costs for PET scans without insurance coverage are around $3,000. Currently Medicare does not cover use of amyloid imaging agents except for in clinical trials. [ 6 ] Because of this, there is a low market for flutemetamol.

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 These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope.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

  8. Theranostics - Wikipedia

    en.wikipedia.org/wiki/Theranostics

    Positron emission tomography (PET) imaging in theranostics provides insight into metabolic and molecular processes within the body. The PET scanner detects photons and creates three-dimensional images that enable visualization and quantification of physiological and biochemical processes. [ 11 ]

  9. Neuroimaging - Wikipedia

    en.wikipedia.org/wiki/Neuroimaging

    Positron emission tomography (PET) and brain positron emission tomography, measure emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream. The emission data are computer-processed to produce 2- or 3-dimensional images of the distribution of the chemicals throughout the brain.
