  2. Piflufolastat F-18 - Wikipedia

    en.wikipedia.org/wiki/Piflufolastat_F-18

    Piflufolastat F-18, sold under the brand name Pylarify among others, is a radioactive diagnostic agent used for positron emission tomography (PET) imaging. [1] [4] [5] It is given by intravenous injection. [1] [4] The most common adverse reactions include headache, altered taste, and fatigue. [4]

  3. 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.

  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. Different tracers are used for various imaging ...

  5. Emission computed tomography - Wikipedia

    en.wikipedia.org/wiki/Emission_computed_tomography

    Types include positron emission tomography (PET) and Single-photon emission computed tomography (SPECT). SPECT is commonly used to diagnose certain diseases. [1] SPECT imaging is conducting by injecting a radioactive probe (or tracer) into the person's blood stream. [1]

  6. 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.

  7. Nuclear medicine - Wikipedia

    en.wikipedia.org/wiki/Nuclear_medicine

    In addition, nuclear medicine scans differ from radiology, as the emphasis is not on imaging anatomy, but on the function. For such reason, it is called a physiological imaging modality. Single photon emission computed tomography (SPECT) and positron emission tomography (PET) scans are the two most common imaging modalities in nuclear medicine. [3]

  8. 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 ...

  9. 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, ...
