Abstract

There was a minor error in the transcription of values to Table 2 in the original manuscript.1 Below is the proper Table 2, only values associated with STEAM and PRESS have been modified. This error had no impact on any of the results within this paper. All authors have approved this change. Table 2 List of relative crusher areas and minimum crushing strength of the unwanted coherence pathways obtained from DOTCOPS for 7 common in vivo MRS pulse sequences. The nomenclature used is the crusher number indicates the gradient which is applied after the corresponding RF pulse, e.g., crusher 1 is applied sometime after RF1 (excitation pulse) and before RF2. For PRESS and STEAM the 2nd crusher is given twice the maximum possible area than the 1st and 3rd crushers, for all other sequences the maximum relative area is equal for all gradients and set equal to 1. Note that any three crusher axes can be swapped, and any axis can be multiplied by negative 1 without changing the overall crushing strength. The minimum crushing strength is the normalized crusher area (i.e., each crusher has an area of 1) that the least affected unwanted coherence pathway is crushed by. A maximum coherence order of 1 was considered (Table presented.) REFERENCES [1] Landheer K, Juchem C.
