Fast 31P chemical shift imaging using SSFP methods.
Steady-state free precession (SSFP) methods have been very successful due to their high signal and short imaging times. These properties make them good candidates for applications that intrinsically suffer from low signal such as low gamma nuclei imaging. A new chemical shift imaging (CSI) technique based on the SSFP signal formation has been implemented and applied to (31)P. The signal propert...
متن کاملEchoplanar chemical shift imaging.
A novel method of chemical shift imaging utilizing echoplanar imaging (EPI) has been developed for the purpose of improving the spatial resolution of metabolite images for the specific goal of high spatial resolution mapping of neuronal content. An EPI sequence was modified to allow temporal offsets of the 180 degree refocusing pulse that encode the chemical shift information into the phase of ...
متن کامل31P NMR of Phospholipid Membranes: Effects of Chemical Shift Anisotropy at High Magnetic Field Strengths
The 31P NMR spectrum of sonicated dipalmitoyl lecithin vesicles consists of two chemically shifted resonances, separated by -0.15 ppm, which arise from phosphate groups in phospholipid molecules on the insideand the outside of the spherical bilayer vesicles. The widths of the resonances are remarkably sensitive to the crystallineliquid crystalline phase transition, the magnetic field-strength, ...
متن کاملAdiabatic Spiral Correlation Chemical Shift Imaging
Introduction The overlap of spectra in magnetic resonance spectroscopy limits the unambiguous identification and quantification of metabolites. Two of the most employed approaches involve fitting with a known basis set [1] and spectral editing [2]. Alternatively, multidimensional correlation spectroscopy [3] does not need to assume a certain basis set, nor needs to filter-out metabolites as in ...
متن کاملNatural linewidth chemical shift imaging (NL-CSI).
The discrete Fourier transform (FT) is a conventional method for spatial reconstruction of chemical shifting imaging (CSI) data. Due to point spread function (PSF) effects, FT reconstruction leads to intervoxel signal leakage (Gibbs ringing). Spectral localization by imaging (SLIM) reconstruction was previously proposed to overcome this intervoxel signal contamination. However, the existence of...
