Quantitative measurement of N-acetyl-aspartyl-glutamate at 3 T using TE-averaged PRESS spectroscopy and regularized lineshape deconvolution.
This article introduces regularized lineshape deconvolution in conjunction with TE-averaged PRESS spectroscopy to measure N-acetyl-aspartyl-glutamate (NAAG). Averaging different echo times suppressed the signals of multiplets from strongly coupled spin systems near 2 ppm; thus, minimizing the interfering signals to detect the acetyl proton signal of NAAG. Signal distortion was corrected by line...
متن کاملN-acetyl-aspartyl-glutamate detection in the human brain at 7 Tesla by echo time optimization and improved Wiener filtering.
PURPOSE To report enhanced signal detection for measuring N-acetyl-aspartyl-glutamate (NAAG) in the human brain at 7 Tesla by echo time (TE) -optimized point-resolved spectroscopy (PRESS) and improved Wiener filtering. METHODS Using a highly efficient in-house developed numerical simulation program, a PRESS sequence with (TE1 , TE2 ) = (26, 72) ms was found to maximize the NAAG signals relati...
متن کاملIn vivo differentiation of N-acetyl aspartyl glutamate from N-acetyl aspartate at 3 Tesla.
A method is described that allows the in vivo differentiation of N-acetyl aspartate (NAA) from N-acetyl aspartyl glutamate (NAAG) by in vivo MR spectroscopy (MRS) at 3 Tesla (3T). The method, which is based on MEGA-point-resolved spectroscopy (PRESS) editing, selectively targets the aspartyl spin system of one species while deliberately removing the other species from the spectrum. This allows ...
متن کاملLCModel Accuracy Testing for N-Acetyl Aspartyl Glutamate Measurement using Phantom Study
INTRODUCTION: NAAG levels play a critical role in various diseases including Alzheimer's disease, schizophrenia and amyotrophic lateral sclerosis (ALS), etc [1-3]. Even though accurate measurements of in vivo NAAG levels are important in defining disease severity and monitoring of treatment outcome, there has been a lack of reliable quantification using MRS. Structurally, NAAG consists of N-ace...
متن کاملLineshape Accommodation in Quantitation of Magnetic Resonance Spectroscopy Signals
Introduction Lineshape distortions due to residual eddy currents and magnetic field inhomogeneities are often present in short echo-time H spectroscopic data. If left uncorrected, these lineshape distortions lead to errors in metabolite concentration estimates when using quantification methods that incorporate model functions with specific lineshapes (i.e., Lorentzian or Gaussian). Several meth...
