The study of Research Fellow Anouk Marsman, Senior Researcher Esben Thade Petersen, Research Fellow Vincent Boer, et al. on prospective motion correction for edited 1H-MRS is now published in NeuroImage! See: https://doi.org/10.1016/j.neuroimage.2021.117922.
We implemented a navigator-based prospective motion correction strategy including reacquisition of corrupted data in conventional and edited MRS. Spectra were acquired without motion, with motion with correction, and with motion without correction. When using both prospective motion correction and retrospective outlier removal, spectral quality was improved to almost the level of the no-motion acquisition and no differences in metabolite levels were observed.
Edited MRS showed to be more sensitive to motion. Prospective motion correction can restore most of the spectral quality in both conventional and edited MRS.
