Saturation prepared quantitative myocardial perfusion imaging particularly depends on an exact determination of the arterial input function (AIF). However, for typical contrast agent doses and recovery times TI between magnetization preparation and image acquisition, this is hampered by saturation effects. Utilizing a model constrained image reconstruction algorithm in conjunction with radial data acquisition, one complete image can be reconstructed for every single acquired radial projection; i.e. every corresponding TI. Hence, the technique allows determining a non-saturated AIF (short TI) and the conventional images (long TI) within one single scan.
