The Assessment of Endolymphatic Hydrops with High-resolution 3D Real Inversion Recovery and 3D Fluid Attenuated Inversion Recovery Sequences
Since the initial study by Nakashima et al. [1] who demonstrated that endolymphatic hydrops in patients with Ménière’s disease can be visualized using MR imaging following an intratympanic injection of gadolinium, this topic has gained strong clinical interest internationally [2–13]. The two most common sequences used in the evaluation of endolymphatic hydrops are a 3D Fluid Attenuated Inversio...
متن کاملInfarct quantification using 3D inversion recovery and 2D phase sensitive inversion recovery, validation in patients and ex vivo
BACKGROUND Cardiovascular-MR (CMR) is the gold standard for quantifying myocardial infarction using late gadolinium enhancement (LGE) technique. Both 2D- and 3D-LGE-sequences are used in clinical practise and in clinical and experimental studies for infarct quantification. Therefore the aim of this study was to investigate if image acquisitions with 2D- and 3D-LGE show the same infarct size in ...
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 کاملComparing Geostatistical Seismic Inversion Based on Spectral Simulation with Deterministic Inversion: A Case Study
Seismic inversion is a method that extracts acoustic impedance data from the seismic traces. Source wavelets are band-limited, and thus seismic traces do not contain low and high frequency information. Therefore, there is a serious problem when the deterministic seismic inversion is applied to real data and the result of deterministic inversion is smooth. Low frequency component is obtained fro...
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...
