Patterns of T2-FLAIR discordance across a cohort of adult-type diffuse gliomas and deviations from the classic T2-FLAIR mismatch sign
PurposeT2-FLAIR mismatch serves as a highly specific but insensitive marker for IDH-mutant (IDHm) astrocytoma with potential limitations in...

Super T2-FLAIR mismatch sign: a prognostic imaging biomarker for non-enhancing astrocytoma, IDH-mutant
PurposeThe T2-FLAIR mismatch sign is a highly specific diagnostic imaging biomarker for astrocytoma, IDH-mutant. However, a definitive prognostic...

Comparison between 3D SPACE FLAIR and 3D TSE FLAIR in Menière’s disease
PurposeHeavily T2-weighted 3D FLAIR (hT 2 w-3D-FLAIR) sequence with constant flip angle (CFA) has been reported as being more sensitive to low...

T2-FLAIR mismatch sign correlates with 11C-methionine uptake in lower-grade diffuse gliomas
PurposeThe T2-FLAIR mismatch sign is recognized as an imaging finding highly suggestive of IDH -mutant astrocytomas. This study was designed to...

Spontaneous intracranial hypotension: Exploring the viability of non-contrast FLAIR as a substitute for contrast-enhanced T1WI in assessing pachymeningeal thickening
PurposeTo avoid contrast administration in spontaneous intracranial hypotension (SIH), some studies suggest accepting diffuse pachymeningeal...

Evaluation of T2W FLAIR MR image quality using artificial intelligence image reconstruction techniques in the pediatric brain
BackgroundArtificial intelligence (AI) reconstruction techniques have the potential to improve image quality and decrease imaging time. However,...

Peritumoral T2/FLAIR hyperintense MRI findings of meningiomas are not necessarily edema and may persist permanently: a systematic review
The current knowledge regarding the prevalence and persistence of edematous changes postmeningioma surgery is limited. Our hypothesis was that...

Added value of delayed post-contrast FLAIR in diagnosis of metastatic brain lesions
BackgroundOne of the drawbacks in contrast-enhanced T1-weighted imaging (CE-T1WI) is the enhancing cortical vessels which can be confused with...

Follow-up infarct volume on fluid attenuated inversion recovery (FLAIR) imaging in distal medium vessel occlusions: the role of cerebral blood volume index
BackgroundDistal medium vessel occlusions (DMVOs) contribute substantially to the incidence of acute ischemic strokes (AIS) and pose distinct...
