Robustness of water fat opposed phase (WFOP) sequence to B0/B1 inhomogeneity was evaluated at 3T quantitatively and qualitatively by comparing with CHESS, and SPAIR. Voxels with unsuppressed fat due to B0 inhomogeneity was fewest for WFOP, and the degree was well presented by inhomogeneity index. Image quality was rated best for SPAIR due to effects of B1 field inhomogeneity in WFOP and CHESS.
