This is often due to a combination of atherosclerosis, demyelination (loss of the "white matter" covering the nerves ), and scarring. How often have you read, "There are small scattered foci of signal abnormalities (T2 hyperintensities or increased FLAIR signal) in the cerebral white matter indicative of demyelinating disease, chronic white matter ischemia due to microvascular disease, or gliosis from an infectious/inflammatory disease process," or words just like them in your Remember that bright doesn't mean "compared to the rest of the scan," it means "compared to how that area is supposed to look." T2-hyperintense foci on brain MR imaging MRI is a sensitive method of CNS focal lesions detection but is less specific as far as their differentiation is concerned. Imaging of the spine in multiple sclerosis. So substances with short T2's have smaller signals and appear darker than substances with longer T2 values. protract adds to prolong implications of needlessness, vexation, or indefiniteness. Areas of new, active inflammation in the brain become white on T1 scans with contrast. Following a radiofrequency pulse, this form of relaxation occurs with the time constant T2, where T2 is the time it takes for the transverse magnetization vector to decay to 1/e or 37% of its initial magnitude. Mri brain was done it showed scattered white matter foci of increased t2 prolongation. In pure water T2 is long, about 3-4 seconds because water molecules move considerably faster than the Larmor frequency. {"url":"/signup-modal-props.json?lang=us"}, Bashir U, Rock P, Murphy A, et al.

Many similar examples of additive (augmenting) or subtractive (competing) image contrasts between two tissue components may be cited. 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). Many of the lesions may not be causing obvious symptoms. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits.
