Postcontrast Fluid-Attenuated Inversion Recovery (FLAIR) Sequence MR Imaging in Detecting Intracranial Pathology

Normal myelination of the pediatric brain imaged with fluid-attenuated inversion-recovery (FLAIR) MR imaging.

BACKGROUND AND PURPOSE As in adult imaging, FLAIR can be applied to pediatric brain imaging, and this requires an appreciation of the normal pediatric brain appearance by FLAIR imaging. The purpose of this study was to describe the MR appearance of the brain in normal infants and young children as demonstrated by fluid-attenuated inversion-recovery (FLAIR) MR imaging. METHODS We retrospective...

Fast fluid-attenuated inversion-recovery MR of intracranial infections.

PURPOSE To assess the usefulness of fast fluid-attenuated inversion-recovery (FLAIR) MR sequences in the diagnosis of intracranial infectious diseases. METHODS We compared fast FLAIR images with conventional spin-echo images (T1- and T2-weighted) obtained in 20 patients with infectious diseases (six with encephalitis, five with brain abscesses, three with meningitis, two with meningoencephali...

Real-flair: Real-part Imaging for Fluid Attenuated Inversion Recovery Sequence

Introduction In magnitude-based inversion recovery (IR) imaging, it is sometimes difficult to set optimum inversion time (TI) for nulling target tissue signals. When TI is shorter than the optimum, contrast reductions or dark line artifacts due to wraparound of negative signals are introduced. A real-part imaging for IR (real-IR) [1-5], providing both positive and negative signals, is a solutio...

Fluid-attenuated inversion recovery now with another acronym: "KRISP FLAIR".

Analysis of cystic intracranial lesions performed with fluid-attenuated inversion recovery MR imaging.

BACKGROUND AND PURPOSE T1-, T2-, and proton density (PD)-weighted sequences are used to characterize the content of cystic intracranial lesions. Fluid-attenuated inversion recovery (FLAIR) MR sequences produce T2-weighted images with water signal saturation. Therefore, we attempted to verify whether FLAIR, as compared with conventional techniques, improves the distinction between intracranial c...
