  2. T2*-weighted imaging - Wikipedia

    en.wikipedia.org/wiki/T2*-weighted_imaging

    T2*-weighted imaging of the brain 26 weeks after subarachnoid hemorrhage, showing hemosiderin deposits as hypointense areas. [1] T 2 *-weighted imaging is an MRI sequence to quantify observable or effective T 2 (T2* or "T2-star"). In this sequence, hemorrhages and hemosiderin deposits become hypointense. [2]

    Standard foundation and comparison for other sequences T2 weighted: T2: Measuring spin–spin relaxation by using long TR and TE times Higher signal for more water content [4] Low signal for fat in standard Spine Echo (SE), [4] though not with Fast Spin Echo/Turbo Spin Echo (FSE/TSE). FSE/TSE is the standard of care in modern medicine because ...

  6. Hyperintensity - Wikipedia

    en.wikipedia.org/wiki/Hyperintensity

    These small regions of high intensity are observed on T2 weighted MRI images (typically created using 3D FLAIR) within cerebral white matter (white matter lesions, white matter hyperintensities or WMH) [1] [2] or subcortical gray matter (gray matter hyperintensities or GMH). The volume and frequency is strongly associated with increasing age. [2]

  7. Magnetic resonance imaging of the brain - Wikipedia

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

    A number of different imaging modalities or sequences can be used with imaging the nervous system: T 1-weighted (T1W) images: Cerebrospinal fluid is dark. T 1-weighted images are useful for visualizing normal anatomy. T 2-weighted (T2W) images: CSF is light, but fat (and thus white matter) is darker than with T 1.

  9. Inversion recovery - Wikipedia

    en.wikipedia.org/wiki/Inversion_recovery

    Inversion recovery is a magnetic resonance imaging sequence that provides high contrast between tissue and lesion. It can be used to provide high T1 weighted image, high T2 weighted image, and to suppress the signals from fat, blood, or cerebrospinal fluid (CSF). [1]
