Arterial spin labeling enables non-invasive quantification of myocardial perfusion. However, there is a need to improve its reproducibility by reducing subtraction errors due to motion and thus, avoiding signal blurring in the acquired low-resolution images. Here, we demonstrate the feasibility of quantifying MBF employing synchronized breathing techniques with FAIR-ASL in healthy subjects. Visually, motion is significantly reduced, MBF values are consistent with those reported in the literature and coefficient of variation for intrasession reproducibility is 13%.
