A sequence with 2D simultaneous multi-slice (SMS) and 3D stack-of-stars (SoS) alternating each heartbeat sequence has been proposed previously1. Here, we increase the heart-coverage of the 2D SMS portion of the scan from 3 slices to 6 slices, to match the coverage of the 3D SoS method. Three minipigs and one healthy volunteer were studied using this method at both adenosine stress and rest cases, and the sequences gave flows with reasonable agreement.
