Echoplanar 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 کاملProton chemical shift imaging in pick complex.
BACKGROUND AND PURPOSE Pick complex (PC) is the name given to a group of diseases comprising Pick disease and its variations, all of which have a large degree of pathologic and clinical overlap. Because of this overlap, the observation of neuropathologic changes in vivo is difficult, although these changes play important roles in the criteria used for classification. The purpose of this study w...
متن کاملMagnetic Resonance Im Spectral resolution enhancement by chemical shift imaging
Three-dimensional chemical shift imaging (3D CSI) with appropriate data postprocessing can be used as a tool to improve spectral resolution in samples where large susceptibility differences and limited shim capabilities prevent good sample shimming. Data postprocessing is reduced to the realignment of individual 3D voxel spectra. As a result, the line broadening due to the field inhomogeneity o...
متن کاملChemical shift imaging (CSI) by precise object displacement.
A mechanical device (NMR lift) has been built to displace vertically an object (typically an NMR sample tube) inside the NMR probe with an accuracy of 1 microm. A series of single pulse experiments are performed for incremented vertical positions of the sample. With a sufficiently spatially selective radio-frequency (r.f.) field, one obtains chemical shift information along the displacement dir...
متن کاملSubcutaneous lipid suppression via variable-density spiral sampling for full cortical coverage in chemical shift imaging
Introduction: Estimates of metabolites in the brain using large-FOV chemical shift imaging (CSI) are severely hampered by strong lipid signals even though the interfering signal arises from subcutaneous tissue. Since SNR in MR is proportional to voxel size [1] the low metabolite concentration, and therefore low SNR in spectroscopic imaging dictates large voxel size, and in turn, the spatial ext...
