We investigated the effect of outer volume saturation (OVS) using very selective saturation pulses (VSS) on metabolite concentrations in PRESS MRS. Our results show that if the PRESS excitation voxel isn’t increased in size, metabolite concentrations are overestimated compared with not using VSS-OVS. These results will be of interest to other researchers planning or conducting multi-centre MRS studies.
