We have compared CBF value agreement in healthy subjects across two readouts, 3D-GraSE and 2D-EPI, and two field strength, 1.5 and 3T, and investigated for which acquisition parameters we can reach the best agreement. Significantly higher GM CBF was observed with a 2D-EPI readout compared to a 3D-GraSE readout with equivalent acquisition resolution (p < 0.005 for 1.5T and p < 0.05 for 3T). A better agreement was observed between 3D-GraSE and 2D-EPI on 3T systems when the resolution of the 3D-GraSE readout was increased to match the effective resolution to the 2D-EPI scan (ICC = 0.772 and ICC = 0.932 respectively).
