The sequence that continuously acquired Golden-angle RAdial Sparse Parallel acquisition employing compressed sensing reconstruction (“GRASP”) can acquire high spatial and high temporal resolution as well as motion robustness to DCE MRI in liver imaging. However, there are still some artifacts in abdominal imaging, especially in the early arterial phase. In this study, we proposed an optimization scheme which can significantly improve the image quality both in plain and all enhanced phases, which may have important value in the study of abdominal disease using GRASP based DCE in future.
