Look-Locker arterial spin labelling (ASL) is used for the measurement of myocardial perfusion in preclinical studies. Saturation effects from Look-Locker acquisition will become particularly relevant in the heart when acquiring multi-slice ASL data, which requires thicker slice-selective inversions and additional RF pulses. In this study, we have taken the preliminary steps toward developing a 3-compartment iterative ASL model for the heart which includes the effects of the Look-Locker acquisition, in order to model the ASL acquisition.
