Imaging spinal osteomyelitis and epidural abscess with short TI inversion recovery (STIR).
MR imaging, primarily the spin-echo technique, is increasingly important in evaluating spinal disease [1-3]. We have found, however, that short TI inversion recovery (STIR) in conjunction with spin-echo techniques provides higher tissue contrast images in shorter imaging times while minimizing imaging degradation due to motion and pulsation. The STIR sequence suppresses the signal from fat [4],...
متن کاملOptimization of inversion time for postmortem short-tau inversion recovery (STIR) MR imaging.
PURPOSE Signal intensity and image contrast differ between postmortem magnetic resonance (PMMR) images and images acquired from the living body. We sought to achieve sufficient fat suppression with short-tau inversion recovery (STIR) PMMR imaging by optimizing inversion time (TI). MATERIAL AND METHODS We subjected 37 deceased adult patients to PMMR imaging at 1.5 tesla 8 to 60 hours after con...
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 ...
متن کاملImaging degeneration of the substantia nigra in Parkinson disease with inversion-recovery MR imaging.
BACKGROUND AND PURPOSE Visualizing with MR imaging and obtaining quantitative indexes of degeneration of the substantia nigra in Parkinson disease have been long-sought goals. We investigated the potential role of area and T1 contrast measurements in differentiating patients from controls and their age-related changes. METHODS Eight patients with Parkinson disease, 8 age-matched controls, and...
متن کاملDifferential diagnosis of vertebral compression fracture using in-phase/opposed-phase and short TI inversion recovery imaging.
BACKGROUND Magnetic resonance imaging (MRI) is highly useful for detecting diseases of the bone marrow. The sensitivity for detecting compression fracture is very high, but specificity is low for differential diagnosis between malignant and benign cases. PURPOSE To evaluate the usefulness of in-phase/opposed-phase and short TI inversion recovery (STIR) magnetic resonance imaging (MRI) of bone...
