Analysis of Methylated Quaternary Ammonium Compounds Using Hydrophilic Interaction Liquid Chromatography Combined With Mass Spectrometry

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Liquid chromatography‐mass spectrometry (LC–MS) is a powerful technique for the detection and quantification of methylated quaternary ammonium compounds (mQACs), such as acylcarnitines and methylated amino‐acid‐derived (betainized) compounds, in biological matrices.

SMART MRS: A Simulated MEGA‐PRESS ARTifacts toolbox for GABA‐edited MRS

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To create a Python‐based toolbox to simulate commonly occurring artifacts for single voxel gamma‐aminobutyric acid (GABA)‐edited MRS data. Methods The toolbox was designed to maximize user flexibility and contains artifact, applied, input/output (I/O), and support functions.

A data‐driven algorithm to determine 1H‐MRS basis set composition

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose Metabolite amplitude estimates derived from linear combination modeling of MR spectra depend on the precise list of constituent metabolite basis functions used (the “basis set”). The absence of clear consensus on the “ideal” composition or objective criteria to determine the suitability of a particular basis set contributes to the poor
