چکیده
designed in [2] for unobstructed Glu and Gln detection with chosen (TE, TM) regions in white boxes for phantom experiments. Fig. 2. In vitro STEAM spectra of Glu and Gln acquired at (72ms, 06 ms) and (84 ms, 58 ms) at 3T and multiplied with a filter to render them representative of typical in vivo line widths. Fig. 3. In vivo STEAM spectra acquired from a voxel including the ACC of a healthy volunteer with the sequence timing parameters of (72 ms, 06 ms) and (84 ms, 58 ms), respectively, at 3T.

Fig.2. STEAM spectra (around 2.54 ppm) of GSH from phantom (black) and simulation (red) at the optimized (TE, TM) = (72 ms,73 ms). The spectrum from phantom was smoothed with a 5-Hz line broadening and the simulated spectrum was also smoothed to match the line width of the phantom spectrum.

متن کاملSimultaneous Quantification of γ-aminobutyric acid, Glutamate, and Glutamine at 3T
BACKGROUND: γ-Aminobutyric acid (GABA), glutamate (Glu) and glutamine (Gln) are three important neurochemicals comprising a tightly coupled spin system. The coupling of this system and their low concentrations in brain typically render GABA MRS-invisible and Glu/Gln indistinguishable (and represented as the composite peak Glx) on standard clinical PRESS scans. Investigations by Hu et al. [1] ha...
متن کاملQuantification of Glutamate and Glutamine using CT-PRESS at 3T
Introduction Glutamate (Glu) and glutamine (Gln) are two major neurochemicals in the central nervous system. Quantifying Glu and Gln in vivo using magnetic resonance spectroscopy (MRS) has been of particular interest to basic science for understanding the Glu/Gln component of the Krebs cycle and its alteration by neuropsychiatric disorders such as Alzheimer’s disease, epilepsy and alcoholism. H...
متن کاملReliability of Glutamate Quantification in Human Nucleus Accumbens Using Proton Magnetic Resonance Spectroscopy at a 70-cm Wide-Bore Clinical 3T MRI System
The human nucleus accumbens is a challenging region to study using proton magnetic resonance spectroscopy (1H-MRS) on a 70-cm wide-bore clinical 3T MRI system. The aim of this study was to investigate the reliability for quantitative measurement of glutamate concentration in the nucleus accumbens using a 70-cm wide-bore clinical 3T MRI. 1H-MRS of the nucleus accumbens was acquired using the Poi...
