Single Echo Time Glutamate Editing at 3 Tesla
Introduction Glutamate plays an important role in normal brain function and in brain disorders. Recently, MRS measurement of total glutamate concentration has been applied to studying several neurological and psychiatric disorders. Short-TE single voxel MRS methods cannot separate glutamate from overlapping resonances at field strengths accessible to most clinical studies. As a result, spectral...

متن کاملTest-retest reliability and reproducibility of short-echo-time spectroscopic imaging of human brain at 3T.
A 1H magnetic resonance spectroscopic imaging study at 3T and short echo time was conducted to evaluate both the reproducibility, as measured by the interscan coefficient of variation (CV), and test-retest reliability, as measured by the intraclass correlation coefficient (ICC), of measurements of glutamate (Glu), combined glutamate and glutamine (Glx), myo-inositol (mI), N-acetylaspartate, cre...
متن کاملReproducibility of phase rotation STEAM at 3T: focus on glutathione.
PURPOSE The purpose of this study was to determine the reproducibility of a very short echo time (TE) phase rotation stimulated echo acquisition mode (STEAM) sequence at 3T with a focus on the detection of glutathione. METHODS Ten healthy subjects were scanned on two separate visits. Spectra were acquired from voxels placed in the anterior and posterior cingulates. Reproducibility was assesse...
متن کاملGABA editing at 3T with Macromolecule Suppression: MEGA-SPECIAL
Introduction. One commonly used method for in-vivo magnetic resonance spectroscopy (MRS) detection of γ-aminobutyric acid (GABA) is the MEGA-PRESS technique [1], which enables direct observation of the GABA resonance at 3.02 ppm. Unfortunately, direct quantification of GABA using MEGA-PRESS is complicated by co-editing of macromolecule (MM) signals, which also resonate at 3.02 ppm [2]. Two meth...
