  2. In vivo magnetic resonance spectroscopy - Wikipedia

    en.wikipedia.org/wiki/In_vivo_magnetic_resonance...

    In vivo magnetic resonance spectroscopy (MRS) is a specialized technique associated with magnetic resonance imaging (MRI). [1] [2]Magnetic resonance spectroscopy (MRS), also known as nuclear magnetic resonance (NMR) spectroscopy, is a non-invasive, ionizing-radiation-free analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's ...

    en.wikipedia.org/wiki/Diffusion-weighted...

    Some more specialized diffusion MRI techniques such as diffusion kurtosis imaging (DKI) have also been shown to predict the response of cancer patients to chemotherapy treatment. [ 43 ] The principal application is in the imaging of white matter where the location, orientation, and anisotropy of the tracts can be measured.

  4. Safety of magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Safety_of_magnetic...

    MRI without contrast agents is the imaging mode of choice for pre-surgical, in-utero diagnosis and evaluation of fetal tumors, primarily teratomas, facilitating open fetal surgery, other fetal interventions, and planning for procedures (such as the EXIT procedure) to safely deliver and treat babies whose defects would otherwise be fatal. [52] [53]

    Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...

  7. Magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    MRI can detect health problems or confirm a diagnosis, but medical societies often recommend that MRI not be the first procedure for creating a plan to diagnose or manage a patient's complaint. A common case is to use MRI to seek a cause of low back pain ; the American College of Physicians , for example, recommends against imaging (including ...

  8. Susceptibility weighted imaging - Wikipedia

    en.wikipedia.org/wiki/Susceptibility_weighted...

    Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images.

  9. Leptomeningeal cancer - Wikipedia

    en.wikipedia.org/wiki/Leptomeningeal_cancer

    Leptomeningeal cancer is a rare complication of cancer in which the disease spreads from the original tumor site to the meninges surrounding the brain and spinal cord. [1] This leads to an inflammatory response, hence the alternative names neoplastic meningitis (NM), malignant meningitis , or carcinomatous meningitis .
