Synthetic b0 correction performs nearly as well as state of the art (topup) at correcting the shape of the b0 and reducing variation in FA caused by distortions. The mutual information (A), mean square difference in FA (B) and difference in FA (C) are shown for pairs of image volumes. PE-A: phase encoding in anterior direction; PE-P: phase encoding in posterior direction; TOPUP-A: topup-corrected PE-A; TOPUP-P: topup-corrected PE-P; Synth-A: synthetic b0-corrected PE-A; Synth-P: synthetic b0-corrected PE-P.
