We developed an automated advanced-single-voxel MRS acquisition protocol at 3T to facilitate acquisition of high-quality spectroscopic data without local MRS expertise. Voxel-based B0 and B1 calibrations were incorporated into the consensus-recommended semi-LASER sequence and combined with automated voxel prescription. Automated B0 and B1 calibrations saved ~4.5min per voxel vs. manual calibrations. All spectra acquired with the automated protocol by rotating MR technologists were usable, while only 83% of those collected with the manual protocol were usable and spectral quality was more variable. The protocol allows automated acquisition of high-quality MRS data with high success rate on a clinical 3T platform.
