Current MR techniques for quantifying hepatic fat through measurement of the proton density fat fraction (PDFF) require a breath hold that many patients find challenging. In this work, we show that when employing single voxel multiecho spectroscopy for measurement of the liver PDFF, breath holding and free breathing acquisitions yield similar results.
