  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. Functional neuroimaging - Wikipedia

    en.wikipedia.org/wiki/Functional_neuroimaging

    Functional magnetic resonance imaging data. Functional neuroimaging is the use of neuroimaging technology to measure an aspect of brain function, often with a view to understanding the relationship between activity in certain brain areas and specific mental functions.

  5. 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.

  6. 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]

  7. Molecular imaging - Wikipedia

    en.wikipedia.org/wiki/Molecular_imaging

    Imaging joint inflammation in an arthritic mouse using positron emission tomography. PET, MRI, and overlaid images of a human brain. Positron emission tomography (PET) is a nuclear medicine imaging technique which produces a three-dimensional image or picture of functional processes in the body. The theory behind PET is simple enough.

  8. Michael E. Phelps - Wikipedia

    en.wikipedia.org/wiki/Michael_E._Phelps

    PET technology has been applied to the early diagnosis and therapeutic responses in lung, colorectal, breast, ovarian, lymphoma, melanoma, and prostate cancers. PET imaging probes of neurotransmitters are used to observe the normal communication between neuronal systems in the brain as well as the alteration of neuronal functions in disease ...

  9. Theranostics - Wikipedia

    en.wikipedia.org/wiki/Theranostics

    Advanced imaging techniques, including magnetic resonance imaging (MRI) and positron emission tomography (PET), allow for the visualization of neuroanatomy, functional connectivity, and molecular changes in the brain. This enables early detection, precise diagnosis, and monitoring of disease progression, facilitating the development of targeted ...
