Signal enhancement in post-processing of multiple-voxel magnetic resonance spectroscopy

摘要

Several methods in signal processing had been implemented in magnetic resonance spectroscopy (MRS) post-processing step to obtain high-quality magnetic resonance (MR) spectra from multiple-voxel MR spectroscopic imaging. Data were acquired using Turbo Spectroscopic Imaging (TSI) with 3 echo-train length. Data post-processing steps involved spectroscopic data processing, unsuppressed-water reference data processing, and reference data correction into spectroscopic data to obtain the spectra with high resolution and signal-to-noise ratio (SNR).
