Auto-calibrated multiband CAIPIRINHA with through-time encoding (tSMS) has been proposed to acquire multiple slices simultaneously without extra reference scans. Reference images are estimated from the consecutive cardiac phases at a lower temporal resolution for subsequent slice separation. We implemented the tSMS method in a myocardial perfusion sequence and explored the feasibility of whole heart perfusion imaging with tSMS and CS reconstruction retrospectively. The preferable in-vivo results demonstrated the whole heart perfusion imaging is feasible using the tSMS+CS method.
