Estimation and Removal of spurious echo Artifacts in single-voxel MRS using Sensitivity Encoding
[article]
2020
medRxiv
pre-print
Purpose: In localized MR spectroscopy, spurious echo artifacts commonly occur when unsuppressed signal outside the volume-of-interest is excited and refocused. In the spectral domain, these signals often overlap with metabolite resonances and hinder accurate quantification. Since the artifacts originate from regions separate from the target MRS voxel, this work proposes that sensitivity encoding based on receive coil sensitivity profiles may be used to separate these signal contributions.
