  2. PET-MRI - Wikipedia

    en.wikipedia.org/wiki/PET-MRI

    With both PET-CT and PET-MR the intended advantage is to combine functional imaging provided by PET, with structural information from CT or MRI. Although images from different modalities collected at different scanning sessions can be overlaid by image registration , a simultaneous acquisition offers better alignment of images and direct ...

  3. Positron emission tomography - Wikipedia

    en.wikipedia.org/wiki/Positron_emission_tomography

    Complete body PET-CT fusion image Brain PET-MRI fusion image. PET scans are increasingly read alongside CT or MRI scans, with the combination (co-registration) giving both anatomic and metabolic information (i.e., what the structure is, and what it is doing biochemically). Because PET imaging is most useful in combination with anatomical ...

  4. Brain positron emission tomography - Wikipedia

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

    PET is probably most useful in early cases of certain dementias (with classic examples being Alzheimer's disease and Pick's disease) where the early damage is too diffuse and makes too little difference in brain volume and gross structure to change CT and standard MRI images enough to be able to reliably differentiate it from the "normal" range ...

  5. Molecular imaging - Wikipedia

    en.wikipedia.org/wiki/Molecular_imaging

    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. First a molecule is tagged with a positron emitting isotope.

  6. Emission computed tomography - Wikipedia

    en.wikipedia.org/wiki/Emission_computed_tomography

    PET is often conducted by having the person consume a drink that includes radioactive isotopes or by having the isotopes injected into a person's bloodstream. These isotopes are absorbed by different tissues in the body, including malignant tumour cells, and PET imaging can visualize the function or detect tumour cells by visualizing how the ...

  7. Preclinical imaging - Wikipedia

    en.wikipedia.org/wiki/Preclinical_Imaging

    Desktopmodells of SPECT, uCT and PET for preclinical use. Preclinical imaging is the visualization of living animals for research purposes, [1] such as drug development. . Imaging modalities have long been crucial to the researcher in observing changes, either at the organ, tissue, cell, or molecular level, in animals responding to physiological or environmental c

  8. 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

  9. PET for bone imaging - Wikipedia

    en.wikipedia.org/wiki/PET_for_bone_imaging

    where, within the tissue region-of-interest from the PET image, C bone (T) is the bone tissue activity concentration of tracer (in units: MBq/ml) at any time T, C plasma (T) is the plasma concentration of tracer (in units: MBq/ml) at time T, V o is the fraction of the ROI occupied by the ECF compartment, and () is the area under the plasma ...
