WebFluid-attenuated inversion recovery (FLAIR) is an inversion-recovery pulse sequence designed to nul-lify or greatly reduce the signal from CSF. It pro-vides heavily T2-weighted images without a very high signal or potential artifacts from CSF (1–6). Clinical applications of the FLAIR technique have been described (3–6), and its clinical utility WebDec 1, 2011 · Three-dimensional fluid attenuated inversion recovery imaging with isotropic resolution and nonselective adiabatic inversion provides improved three-dimensional …

WebJun 23, 2015 · The signal changes predominate in the periventricular and deep white matter, so were commonly referred to originally as “white matter lesions” although they are also recognized to occur in the deep gray matter. 6 These areas are hyperintense on T2-weighted (T2), proton density-weighted (PD), and fluid attenuated inversion recovery … WebJul 14, 2024 · Multiple sclerosis (MS) is an inflammatory, demyelinating autoimmune disease of the central nervous system (CNS). Its pathophysiological processes lead to focal lesions in the brain, which are detectable using MRI. 1 Standard MRI protocols comprise native and contrast-enhanced T 1-weighted imaging, proton fluid attenuated inversion … WebFluid-attenuated inversion recovery (FLAIR) [2] is an inversion-recovery pulse sequence used to nullify the signal from fluids. For example, it can be used in brain imaging to suppress cerebrospinal fluid so as to bring out periventricular hyperintense lesions, such as multiple sclerosis plaques. how to scan an entire document
