A radial IR-SPGR pulse sequence with bipolar readouts is demonstrated along with a model-based iterative reconstruction to simultaneously map high resolution composite and water-only T₁ and proton density fat fraction (PDFF) in the abdomen. The proposed pulse sequence and reconstruction algorithm can yield high-quality T₁ and PDFF maps in 2.5 seconds/slice. The resulting maps have an in-plane resolution of 1.25mm and through-plane resolution of 5.00mm. When combined with selective inversion pulse, the technique achieves multi-slice imaging for breath-hold studies.
