  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]

    Alternative methods of medical imaging include single-photon emission computed tomography (SPECT), computed tomography (CT), magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI), and ultrasound. SPECT is an imaging technique similar to PET that uses radioligands to detect molecules in the body. SPECT is less ...

    PET imaging with 18F-FDG takes advantage of the fact that the brain is normally a rapid user of glucose. Standard 18F-FDG PET of the brain measures regional glucose use and can be used in neuropathological diagnosis. Example: Brain pathologies such as Alzheimer's disease greatly decrease brain metabolism of both glucose and oxygen in tandem ...

    en.wikipedia.org/wiki/Medical_imaging

    Medical imaging techniques produce very large amounts of data, especially from CT, MRI and PET modalities. As a result, storage and communications of electronic image data are prohibitive without the use of compression.

  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 generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.

  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.
