Juxtacortical Spots on Fluid-Attenuated Inversion Recovery Images in Cryptogenic Transient Ischemic Attack
BACKGROUND AND PURPOSE Juxtacortical spots are detected frequently on fluid-attenuated inversion recovery (FLAIR) images, but have not been extensively researched in patients with transient ischemic attack (TIA). We hypothesized that juxtacortical spots on FLAIR images are partly associated with right-to-left shunt (RLS) in TIA without clear etiology. The possibility of an association between t...
متن کاملClinical significance of fluid-attenuated inversion recovery vascular hyperintensities in transient ischemic attack.
BACKGROUND AND PURPOSE Fluid-attenuated inversion recovery vascular hyperintensity (FVH) is often identified in patients with acute ischemic stroke. The purpose of this study was to determine the clinical significance of FVH in patients with transient ischemic attack (TIA). METHODS Consecutive inpatients with TIA who underwent MRI within 24 hours of symptom onset were studied. The frequency, ...
متن کاملMemory dysfunction in multiple sclerosis corresponds to juxtacortical lesion load on fast fluid-attenuated inversion-recovery MR images.
BACKGROUND AND PURPOSE MR imaging is a sensitive diagnostic tool and paraclinical marker of disease activity and prognosis in multiple sclerosis (MS), yet the role of MR imaging of MS is controversial. The aim of this study was to describe the relationship between cognitive function and MS lesion size and position, as shown on comparative images from conventional spin-echo (CSE) and fast fluid-...
متن کاملFluid-attenuated inversion recovery magnetic resonance imaging detects cortical and juxtacortical multiple sclerosis lesions.
BACKGROUND Autopsy studies showed cortical and juxtacortical multiple sclerosis (MS) plaques. Fluid-attenuated inversion recovery (FLAIR) is an advanced magnetic resonance imaging sequence that reveals tissue T2 prolongation with cerebrospinal fluid suppression, allowing detection of superficial brain lesions. OBJECTIVES To assess FLAIR, T1-weighted, and T2-weighted images for detecting lesio...
متن کاملFluid-attenuated inversion recovery images and stroke outcome after thrombolysis.
BACKGROUND AND PURPOSE We investigated if hyperintensities on fluid-attenuated inversion recovery (FLAIR) sequences in arteries and parenchyma are associated with poor outcome 3 months after thrombolysis. METHODS Consecutive acute stroke patients with known time of symptom onset who had an MRI before and 1 day after thrombolysis were included in this study. Blinded to follow-up imaging and ou...
