Despite its superb fat suppression characteristics, Dixon TSE is known to be sensitive to motion artifacts. In this study we investigated a novel partial averaging approach for Dixon TSE acquisition, where the k-space center was sampled denser compared to the k-space periphery and randomization was used. Simulation, phantom and volunteer experiments demonstrate the reduced motion ghosting and show that it outperforms the longer two average scans.
