MR 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 کاملEvaluation of the Chondromalacia Patella Using a Microscopy Coil: Comparison of the Two-Dimensional Fast Spin Echo Techniques and the Three-Dimensional Fast Field Echo Techniques
OBJECTIVE We wanted to compare the two-dimensional (2D) fast spin echo (FSE) techniques and the three-dimensional (3D) fast field echo techniques for the evaluation of the chondromalacia patella using a microscopy coil. MATERIALS AND METHODS Twenty five patients who underwent total knee arthroplasty were included in this study. Preoperative MRI evaluation of the patella was performed using a ...
متن کاملFull-brain T1 mapping through inversion recovery fast spin echo imaging with time-efficient slice ordering.
Brain T1 mapping has important clinical applications in detecting brain disorders. Conventional T1 mapping techniques are usually based on inversion recovery spin echo (IRSE) imaging or its more time-efficient counterpart inversion recovery fast spin echo (IRFSE) imaging because they can deliver good image quality. Multiple inversion times are required to accurately estimate T1 over a wide rang...
متن کاملComparison of Fast Recovery Fast Spin Echo and Conventional Fast Spin Echo for T2 Weighted Imaging of the Prostate Gland
Introduction The FRFSE sequence is a modification to the standard FSE sequence in which additional RF pulses are used to accelerate recovery of longitudinal magnetization after the echo train is acquired. The sequence can provide enhanced fluid signal in the setting of short TR for joint imaging. We compared this sequence to standard FSE using a long TR for axial endorectal coil T2 weighted ima...
متن کاملFast Spin Echo Imaging
In conventional spin echo (SE) imaging, the longitudinal magnetization (that is generated by the presence of the main magnetic field, B0) is tipped into the transverse plane using a radiofrequency (RF) pulse that tips the magnetization 90 degrees. Once in the transverse plane, the magnetization rotates, or precesses, around the axis of the main magnetic field. As the transverse magnetization pr...
