  2. Fluid-attenuated inversion recovery - Wikipedia

    en.wikipedia.org/wiki/Fluid-attenuated_inversion...

    Fluid-attenuated inversion recovery (FLAIR) is a magnetic resonance imaging sequence with an inversion recovery set to null fluids. For example, it can be used in brain imaging to suppress cerebrospinal fluid (CSF) effects on the image, so as to bring out the periventricular hyperintense lesions, such as multiple sclerosis (MS) plaques.

  3. Diffusion-weighted magnetic resonance imaging - Wikipedia

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

    Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that enables the measurement of the restricted diffusion of water in tissue in order to produce neural tract images instead of using this data solely for the purpose of assigning contrast or colors to pixels in a cross-sectional image.

  4. Magnetic resonance imaging of the brain - Wikipedia

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

    Diffusion-weighted images (DWI): DWI uses the diffusion of water molecules to generate contrast in MR images. Proton density (PD) images: CSF has a relatively high level of protons, making CSF appear bright. Gray matter is brighter than white matter. [27] False color MRI by applying red to T1, green to PD and blue to T2.

  5. 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.

  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.

  7. Diffuse axonal injury - Wikipedia

    en.wikipedia.org/wiki/Diffuse_axonal_injury

    Diffuse axonal injury after a motorcycle accident. MRI after 3 days: on T1-weighted images the injury is barely visible. On the FLAIR, DWI and T2*-weighted images a small bleed is identifiable. DAI is difficult to detect since it does not show up well on CT scans or with other macroscopic imaging techniques, though it shows up microscopically. [9]

    Phase-contrast magnetic resonance imaging: PC-MRA: Two gradients with equal magnitude, but opposite direction, are used to encode a phase shift, which is proportional to the velocity of spins. [29] Detection of aneurysm, stenosis, or dissection (pictured). [28] ^
