Free-breathing dynamic contrast-enhanced liver MRI is explored using a Cartesian spoiled Volume-Interpolated Breath-hold Examination (VIBE) GRE sequence that also acquires a navigation signal. Images are iteratively reconstructed using a hard-gating approach as well as resolving the motion-states using an additional dimension. With both approaches yielding promising results, the latter appears to be more motion robust at the cost of computational effort.
