Synopsis

3D view-sharing sequence has been demonstrated its great promise for abdominal 4D-MRI due to its high temporal resolution and availability in clinical scanners. However, the sub-optimal use of these sequence in free-breathing situation deteriorates the image quality by ghost artifacts induced by respiration. We propose a novel technique, Retrospective Motion Artifacts Suppression by Simulated radial K-space (R-MASSK), to suppress motion artifacts and to increase image quality of the 4D-MRI acquired by the 3D view-sharing sequences, TRICKS and TWIST, through simulated radial k-space resampling.
