Fluid-attenuated inversion recovery sequences
WebExaminations of the peripheral blood, bone marrow, and cerebrospinal fluid showed no recurrent leukemic cells. Magnetic resonance (MR) imaging of the brain disclosed unexpected CDST at the left transverse sinus, which was seen only on the fast fluid-attenuated inversion recovery (FLAIR) sequence. 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 …

Initial clinical experience in MR imaging of the brain with a fast fluid … 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.
WebMar 1, 2005 · BACKGROUND AND PURPOSE: Contrast-enhanced fluid-attenuated inversion recovery (FLAIR) imaging has been reported to have higher sensitivity for detecting leptomeningeal disease compared with contrast-enhanced T1-weighted MR imaging. The purpose of this study was to compare contrast-enhanced T1-weighted MR … WebFeb 23, 2024 · The term SWI is colloquially used to denote high-spatial-resolution susceptibility-enhanced sequences across different MRI vendors and sequences, although SWI postprocessing was not necessarily performed. SWI-derived phase information helps to discriminate blood products from calcification.
WebHowever, fluid-attenuated inversion recovery was useful in the identification of inflammatory and metabolic disorders. Conclusion: Rapid sequence MRI can be utilized as a screening imaging modality in children with suspected brain attacks in cases where there may be delays in obtaining full sequence brain imaging.
