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 کاملMR evaluation of vertebral metastases: T1-weighted, short-inversion-time inversion recovery, fast spin-echo, and inversion-recovery fast spin-echo sequences.
PURPOSE To compare the detectability of vertebral metastatic disease on T1-weighted, short-inversion-time inversion recovery (STIR), fast spin-echo (FSE), fat-saturated FSE, and inversion recovery FSE (IRFSE) MR sequences using percent contrast and contrast-to-noise ratios. METHODS Patients with proved metastatic disease underwent imaging on a 1.5-T MR system with sagittal T1-weighted (800/20...
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 کاملFast Fluid - Attenuated Inversion - Recovery MR Image in the Intracranial Tumors : Comparison with Fast Spin - echo Image
Purpose : To evaluate the significance of fluid-attenuated inversion recovery (FLAIR) magnetic resonance(MR)images for the diagnosis of intracranial tumors. Materials & Methods : MR imaging was used to study 15 patients with various intracranial tumors and were compared the findings according to fast spin echo and fast FLAIR images . Resu Its : In 12 of 15 patients, tumor signal intensities on ...
متن کاملSpectral Adiabatic Inversion Recovery (SPAIR) MR imaging of the Abdomen
Magnetic resonance imaging (MRI) has become a major imaging tool for the depiction and characterization of abdominal disease. Standard abdominal MRI protocols encompass different forms of T1-weighted (T1w) and T2-weighted (T2w) data acquisition. These sequences can be collected in less than 20 seconds, which typically is within the patients’ ability to suspend respiration. Hence, artifacts due ...
