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...
متن کاملPreliminary evaluation of fluid-attenuated inversion-recovery MR in the diagnosis of intracranial tumors.
PURPOSE To report our preliminary results in the application of a turbo fluid-attenuated inversion-recovery (FLAIR) MR technique to the diagnosis of intracranial tumors and to assess the clinical usefulness of this technique. METHODS Thirty-four patients with various intracranial tumors were studies with MR imaging, including a turbo FLAIR sequence. FLAIR images were compared with images obta...
متن کاملMR of the spine with a fast T1-weighted fluid-attenuated inversion recovery sequence.
PURPOSE To optimize a T1-weighted fast fluid-attenuated inversion recovery (FLAIR) sequence using computer-simulated data and to study its clinical utility for imaging the spine. METHODS Relative signal intensities and contrast of relevant normal and pathologic tissues in the spine were computed using an inversion recovery equation modified to account for a hybrid RARE (rapid acquisition with...
متن کاملThe low sensitivity of fluid-attenuated inversion-recovery MR in the detection of multiple sclerosis of the spinal cord.
PURPOSE To confirm the expected superiority of fluid-attenuated inversion-recovery (FLAIR) over conventional fast spin-echo MR imaging in the detection of multiple sclerosis (MS) of the spinal cord. METHODS Fifteen subjects with known MS involving the spinal cord and brain were studied prospectively. The entire cord was imaged with a phased-array coil on a 1.5-T MR system. Sagittal T1-weighte...
متن کاملNormal 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...
