This work demonstrates abdominal proton density fat fraction (PDFF)-MRI quantification at 7T magnetic field. Four healthy volunteers with low liver fat infiltration assumption were measured with a 3D-MGE-T1w sequence using 32-channel Rx/Tx array coil at 7T whole body MR scanner. 7T data were reconstructed by complex-based multiecho water-fat separation methods. The same volunteers were measured at a 3T MR system with multiecho Dixon MRI and multiecho single voxel MRS as reference measurements. The results show the feasibility of quantitative liver imaging at 7T.
