High-resolution myocardial perfusion imaging offers improved delineation of subendocardial ischemic regions and can lead to improved diagnosis. Here we use undersampled radial simultaneous multi-slice (SMS) acquisitions in conjunction with constrained reconstruction with temporal total variation and spatial block-matching 3D (BM3D) constraints to obtain high in-plane spatial resolution perfusion imaging. Promising results are shown with two types of myocardial perfusion acquisitions (i) a set of 3 simultaneous slices after a saturation pulse, repeated several times per beat at different cardiac phases, and (ii) a ‘hybrid’ perfusion acquisition with one saturation pulse per beat and the reconstructed cardiac phase of the 3 slices chosen retrospectively.
