Fast CT-PRESS-based spiral chemical shift imaging at 3 Tesla.
A new sequence is presented that combines constant-time point-resolved spectroscopy (CT-PRESS) with fast spiral chemical shift imaging. It allows the acquisition of multivoxel spectra without line splitting with a minimum total measurement time of less than 5 min for a field of view of 24 cm and a nominal 1.5x1.5-cm2 in-plane resolution. Measurements were performed with 17 CS encoding steps in ...

متن کاملFast parallel spiral chemical shift imaging at 3T using iterative SENSE reconstruction.
Spiral chemical shift imaging (CSI) is a fast CSI technique that simultaneously encodes 1D spectral and 2D spatial information. Therefore, it potentially allows one to perform a 2D-CSI experiment in a single shot. However, for most applications, limitations on maximum gradient strength and slew rate make multiple excitations necessary in order to achieve a desired spectral bandwidth. In this wo...
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 کاملFast gradient-echo chemical-shift imaging.
A fast chemical-shift imaging using the gradient-echo technique is proposed for the separation of the water and fat in human in vivo imaging. This technique also incorporates magnetic field inhomogeneity correction in the fast chemical-shift imaging. Experimental results of the proposed imaging technique demonstrate that the method would be useful for quick in vivo water-fat separation imaging ...
