While Dixon provides superb fat suppression over large imaging volumes, motion can be a challenge in specific anatomies. This work evaluates a comprehensive approach to reduce motion artifacts in Dixon TSE and FFE sequences, combining a novel Dixon decorrelation approach, partial averaging, modulus in-phase (IP) – out-phase (OP) combinations and saturation of the physiological motion artifact sources by the means of saturation pulses and variable refocusing flip angle sweeps. We are able to show that this approach allows us to effectively remove motion artifacts improving the diagnostic quality of Dixon scans.
