The newly developed radial k-t SPARSE SENSE (RASPS) technique make it possible to further speed up the acquisition and increase the coverage with high temporal/spatial resolution without sacrificing SNR. In this study, we have incorporated dynamic 4D stack-of-star hybrid radial acquisitions with RASPS into this 5-min protocol, and the results of comparisons between RASPS and the previous approach using GRAPPA/TGRAPPA (PAT) for PERF, CINE and LGE imaging are presented.
