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.
