Spurious echo artifacts appear in MRS spectra and originate from regions of unsuppressed and insufficiently crushed signal. We propose a reconstruction method to remove such artifacts using the sensitivity weighting of the receive channels at each spatial location. Data from phantom and simulations show that spurious echoes can be separated from underlying signal. The spatial distribution of unwanted signal was estimated in vivo using B0 maps. Artifactual components of the signal were identified in sinus regions, however not entirely removed from the spectrum. Further work will aim to improve the conditioning of the SENSE reconstruction to remove spurious echo artifacts from MRS data.
