Inspired by Multitasking, we have developed a fast reconstruction method for 3D stack-of-star (SoS) acquisitions to achieve high temporal resolution (0.1s) DCE MRI without additional navigator data. The proposed method is fully compatible with existing sequence using 3D SoS trajectories, but with less computation complexity.
