The effect of the Look-Locker readout scheme on myocardial perfusion measurement applying ASL methods based on T1 mapping is investigated. Furthermore, the effect of partially inverting the left ventricular blood during the slice selective inversion is considered. Significant influence of each issue on the obtained perfusion is found.
