Images of fat-water separation can be obtained by combining the Dixon method and the balanced steady-state free precession (bSSFP) sequence, which is termed as SSFP Dixon method. The application of this method was successful at regions of relatively homogeneous B0. Another variant of this method was the dual-TR method, which was anticipated to have a better immunity to the shimming condition. In this study, we validated this concept with experiments of both methods at regions with significant B0 inhomogeneity.
