We propose Continuous Radial Interleaved simultaneous Multi-slice acquisitions at sPoiled steady-state (CRIMP) for whole-heart, ungated, free-breathing myocardial perfusion assessment. The simultaneous multi-slice (SMS) sequence captures multiple cardiac phases in all image slices simultaneously and keeps the inner slices at steady-state. We use a patch-based motion-compensated locally low-rank method to reconstruct the images. Quantitative perfusion analysis was also performed with an arterial input function estimated from a separate low-dose injection.
