  2. PET-MRI - Wikipedia

    en.wikipedia.org/wiki/PET-MRI

    Positron emission tomography–magnetic resonance imaging (PET–MRI) is a hybrid imaging technology that incorporates magnetic resonance imaging (MRI) soft tissue morphological imaging and positron emission tomography (PET) functional imaging. [1] The combination of PET and MRI was mentioned in a 1991 Phd thesis by R. Raylman. [2]

  3. 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 ...

  4. Brain positron emission tomography - Wikipedia

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

    C030. 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.

  5. 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.

  6. Magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing ...

  7. Cardiac PET - Wikipedia

    en.wikipedia.org/wiki/Cardiac_PET

    OPS-301 code. 3-741. Cardiac PET (or cardiac positron emission tomography) is a form of diagnostic imaging in which the presence of heart disease is evaluated using a PET scanner. Intravenous injection of a radiotracer is performed as part of the scan. Commonly used radiotracers are Rubidium-82, Nitrogen-13 ammonia and Oxygen-15 water.

  8. Emission computed tomography - Wikipedia

    en.wikipedia.org/wiki/Emission_computed_tomography

    Emission computed tomography (ECT) is a type of tomography involving radioactive or emissions. 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 ...

  9. 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 (tracer), which is introduced into the body on a biologically active ...
