  2. Diffusion-weighted magnetic resonance imaging - Wikipedia

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

    Diffusion-weighted magnetic resonance imaging (DWI or DW-MRI) is the use of specific MRI sequences as well as software that generates images from the resulting data that uses the diffusion of water molecules to generate contrast in MR images.

  3. Susceptibility weighted imaging - Wikipedia

    en.wikipedia.org/.../Susceptibility_weighted_imaging

    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.

    en.wikipedia.org/wiki/Magnetic_resonance_imaging...

    The first MR images of a human brain were obtained in 1978 by two groups of researchers at EMI Laboratories led by Ian Robert Young and Hugh Clow. [1] In 1986, Charles L. Dumoulin and Howard R. Hart at General Electric developed MR angiography, [2] and Denis Le Bihan obtained the first images and later patented diffusion MRI. [3]

    Functional MRI (fMRI) Blood-oxygen-level dependent imaging: BOLD: Changes in oxygen saturation-dependent magnetism of hemoglobin reflects tissue activity. [26] Localizing brain activity from performing an assigned task (e.g. talking, moving fingers) before surgery, also used in research of cognition. [27] Magnetic resonance angiography (MRA ...

    For example, imaging of prostate tumors is better accomplished using T2-MRI and DWI-MRI than T2-weighted imaging alone. [7] The number of applications of mpMRI for detecting disease in various organs continues to expand, including liver studies, breast tumors , pancreatic tumors , and assessing the effects of vascular disruption agents on ...

  7. 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.

    The MRI machine looked pretty standard, except that there was a screen with Netflix queued up. The facilitator put a weighted cover (almost like a blanket) over my legs and chest so I stayed still.

  9. Watershed stroke - Wikipedia

    en.wikipedia.org/wiki/Watershed_stroke

    An MRI with special sequences called diffusion-weighted MR imaging (DWI), is very sensitive for locating areas of an ischemic based stroke, such as a watershed stroke. Further diagnosis and evaluation of a stroke includes evaluation of the blood vessels in the neck using either Doppler ultrasound, MR-angiography or CT-angiography, or formal ...
