PURPOSE Three-dimensional (3 D) MRI sequences allow improved spatial resolution with good signal and contrast properties as well as multiplanar reconstruction. We sought to compare Cube, a 3 D FLAIR sequence, to a standard 2 D FLAIR sequence in multiple sclerosis (MS) imaging. MATERIALS AND METHODS Examinations were performed in the clinical routine on a 3.0 Tesla scanner. 12 patients with de...

Ziel: Dreidimensionale MRT-Sequenzen erlauben sowohl eine verbesserte räumliche Auflösung bei guten Signalund Kontrasteigenschaften als auch multiplanare Rekonstruktionen. Wir verglichen Cube, eine 3-D-FLAIR-Sequenz, mit einer Standard-2D-FLAIR-Sequenz bei der Bildgebung der multiplen Sklerose (MS). Material und Methoden: Die Untersuchungenwurden an einem 3-Tesla-Scanner in der klinischen Routi...

BACKGROUND AND PURPOSE FLAIR and double inversion recovery are important MR imaging scans for MS. The suppression of signal from CSF in FLAIR and the additional suppression of WM signal in double inversion recovery improve contrast between lesions, WM and GM, albeit at a reduced SNR. However, whether the acquisition of double inversion recovery is necessary is still debated. Here, we present an...

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...

purpose: suitable magnetic resonance imaging (mri) techniques from conventional to new devices can help physicians in diagnosis and follow up of multiple sclerosis (ms) patients. the aim of present research was to compare effectiveness of fluid attenuation inversion recovery (flair) sequence of conventional mri and diffuse weighted imaging (dwi) sequence as a new technique in detection of brain...

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...

BACKGROUND AND PURPOSE Fluid-attenuated inversion recovery (FLAIR) MR imaging has advantages to detect meningeal lesions. FLAIR MR imaging was used to detect pachymeningeal thickening and thin bilateral subdural effusion/hematomas in patients with spontaneous intracranial hypotension (SIH). MATERIALS AND METHODS Eight patients were treated under clinical diagnoses of SIH. Chronologic MR imagi...

BACKGROUND AND PURPOSE It has recently been proposed that fluid-attenuated inversion recovery (FLAIR) imaging may serve as a surrogate marker for time of symptom onset after stroke. We assessed the hypothesis that FLAIR imaging could be used to decide if an MRI was performed within 4.5 hours from symptom onset or later. METHODS All consecutive patients with presumed stroke who underwent an MR...

Design innovations and government-sponsored financial incentives are making solar energy increasingly attractive to homeowners and institutional customers such as school districts. In particular, the passive solar design concept of daylighting is gaining favor among educators due to evidence of improved performance by students working in daylit classrooms. Electricity-generating photovoltaic sy...
