Comparison of 2D-GRE T1ρ maps acquired in vivo for 1 participant using tailored VFA scheduling and MAPSS. The left-hand panel images were acquired without CSF nulling, and the right-hand panel images were acquired with CSF nulling. The scan time was the same for all T1ρ maps acquired at a given VPS setting, and the phase-encoding direction was right/left. The improved SNR efficiency of tailored VFA scheduling is apparent and becomes more pronounced at higher VPS. Furthermore, there is no appreciable loss in quantitative accuracy of the T1ρ maps using tailored VFA scheduling. However, there is some loss in spatial fidelity as VPS increases. The 2D T1ρ maps for all participants are shown in Supporting Information Figure S3
