This study presents multi-slice cardiac arterial spin labelling using a new method of myocardial blood flow (MBF) quantification with blood pool magnetization measurement (bpMBF quantification). For bpMBF quantification, a direct measurement of the left-ventricle blood pool magnetization was used to approximate the blood input function into the Bloch equations. Simulation and in vivo results show that bpMBF quantification is robust to variations in slice-selective thickness and therefore applicable to multi-slice acquisition, whereas traditional methods are likely to underestimate multi-slice perfusion. This technique is applied to generate the first multi-slice MBF maps using cardiac arterial spin labelling.
