Short-echo-time H MRS of the mouse lacking brain-specific glutamate-dehydrogenase
Introduction The abundance of genetic models for studying normal function and malfunction of the brain implicates the study of mouse brain by magnetic resonance, which is a method uniquely suited to translate these measurements to humans. Glutamate (Glu) is the major excitatory neurotransmitter and its maintenance is critical for normal function. Glutamate-dehydrogenase (GDH), along with aspart...
متن کاملLocalized in vivo human 1H MRS at very short echo times.
A new point-resolved spectroscopy (PRESS) sequence was developed that allows localized human proton MR spectra to be acquired at echo times (TEs) of 10 ms or less. The method was implemented on a 4 Tesla Varian research console and a clinical 3 Tesla Siemens Trio scanner. Human brain spectra acquired in vivo from the prefrontal cortex at TE=8 ms showed improved signals from coupled resonances (...
متن کاملDiffusion-Weighted Spectroscopy: A Novel Approach to Determine Macromolecule Resonances in Short-Echo Time H-MRS
Quantification of short-echo time proton magnetic resonance spectroscopy results in >18 metabolite concentrations (neurochemical profile). Their quantification accuracy depends on the assessment of the contribution of macromolecule (MM) resonances, previously experimentally achieved by exploiting the several fold difference in T1. To minimize effects of heterogeneities in metabolites T1, the ai...
متن کاملDependency and (R)MRS
Note: for current purposes, this document lacks a proper introduction, in that it assumes readers know about MRS and RMRS. The MRS and RMRS languages are successful in allowing grammar writers to construct underspecified compositional semantics for a variety of languages. They can be used with feature structure formalisms, but also in a separate semantic module with other styles of syntax. RMRS...
