Short TE STEAM is an appealing MRS sequence especially for the quantification of low-concentration J-coupled spin systems. However, in comparison to sLASER, STEAM is associated with larger chemical shift displacement errors in all three directions. With an inhomogeneous B1+-field, slice profiles degrade, resulting in artefacts from extracranial lipids. Here we demonstrate that lipid artefacts can be removed through the use of an external crusher coil. Without use of the crusher coil, large extracranial lipid artefacts are present when selecting a large voxel. Upon activation of the crusher coil, these signals are eliminated, yielding 1H spectra free of large baseline distortions.
