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 ...

2D Diffusion Weighted Chemical Shift Imaging of Brain Metabolites at 7T

Introduction: Diffusion-weighted and diffusion tensor spectroscopy (DWS, DTS) of brain metabolites such as N-acetyl aspartate (NAA), creatine and choline have been shown capable of providing microstructural information that is specific to compartmental geometry in which they reside [1-4]. So far, all DWS and DTS studies have been performed as single volume (SV) scans where accurate calculations...

Na Chemical Shift Imaging of myocardial edema

Introduction – Distinction between viable and non-viable myocardium is essential for diagnosis and treatment of patients with coronary artery disease. Delayed contrast-enhanced (DCE) MRI has become the gold standard to determine the size of chronic infarcts. However, although T2-weigthed MRI shows great promise to delineate the area at risk after the event related to the formation of edema, the...

Adiabatic 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 ...

Natural 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...
