摘要

为了从多体素磁共振成像中获得高质量的磁共振波谱，在磁共振波谱后处理步骤中采用了几种信号处理方法。数据采集采用3回声序列长度的涡轮光谱成像(TSI)。数据后处理步骤包括光谱数据处理、非抑制水参考数据处理、参考数据校正为光谱数据，以获得高分辨率、高信噪比的光谱。

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

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).
