Optimization 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 کاملComparison of Cartesian and radial acquisition on short-tau inversion recovery (STIR) sequences in breast MRI
OBJECTIVE The purpose of this study was to compare two short-tau inversion recovery (STIR) sequences, Cartesian and radial (BLADE) acquisitions, for breast magnetic resonance imaging (MRI) examinations. MATERIALS AND METHODS Ninety-six women underwent 1.5 T breast MRI exam (48 Cartesian and 48 BLADE). Qualitative analysis including image artifacts, image quality, fat-suppression, chest-wall d...
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 کاملInversion Recovery Balanced SSFP: T1 and T2 Measurement Simulation
In this report, inversion recovery (IR) balanced SSFP with the α/2 preparation pulse is simulated for the ideal case where the spin resonant frequency corresponds to the middle of the passband in the balanced SSFP steady-state signal profile. Simulation studies are presented to assess the effects of various choices of T1, T2, and flip angles on the transient signal responses of the IR balanced ...
