Mapping R1 of fat, R1 of water, joint R2⁎, and proton density fat fraction at 3 T using the multi-echo MP2RAGE sequence.
PURPOSE To develop a technique for joint measurement of fat and water-specific longitudinal relaxation rates (R1f and R1w), effective transverse relaxation rate (R2∗), and proton density fat fraction (PDFF) combining the Multi-Echo Magnetization Prepared Two Rapid Acquisition of Gradient Echoes (ME-MP2RAGE) sequence an...
