↵a SOC is superior to FAST for all criteria (P values <.001). Numbers higher than 3 represent preference for the first of the 2 sequences listed in the upper row. FAST-DL is superior to SOC for all criteria (P values < .008), except for GM/WM differentiation. While this metric trended to be superior for FAST-DL versus SOC, it did not reach statistical significance after Bonferroni correction (P = .009). FAST-DL is superior to FAST for all criteria (P values <.001).
