T2-weighted flair
WebSep 1, 1999 · As with T1- and T2-weighted imaging, FLAIR imaging displays signal changes in the peripheral white matter of the cerebral hemispheres after that seen in the deep white matter. As a result, the peripheral white matter in the temporal lobes is one of the last areas to undergo myelination. It remained hyperintense relative to adjacent gray matter ... WebOct 4, 2024 · Fluid-attenuated inversion recovery (FLAIR) is an MRI technique that shows areas of tissue T2 prolongation as bright while suppressing (darkening) cerebrospinal fluid (CSF) signal, thus clearly revealing lesions in proximity to CSF, such as cerebral cortical lesions. What causes T2 FLAIR signal abnormality?
