WEBJun 2, 2023 · Fluid attenuated inversion recovery (FLAIR) is a special inversion recovery sequence with a long inversion time. This removes signal from the cerebrospinal fluid in the resulting images 1 . Brain tissue on FLAIR images appears similar to T2 weighted images with grey matter brighter than white matter but CSF is …

Fluid-attenuated inversion recovery - Wikipedia
https://en.wikipedia.org/wiki/Fluid-attenuated_inversion_recovery
WEBFluid-attenuated inversion recovery (FLAIR) is an MRI 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.

WEBJul 1, 1996 · FLAIR and its variations 10111213 are MRI sequences that produce both a strongly T 2 -weighted image and suppressed CSF signal. To accomplish these twin goals, a conventional SE sequence is prefaced by a 180° inversion pulse. A relatively long TI is used to allow the longitudinal magnetization of CSF to return to the null point before SE …
