This work describes method to correct for saturation in the arterial input function (AIF) for cardiac perfusion using a multi-shot radially acquired data. Single cardiac cycle resolution T1 mapping is possible with this technique. T1 can then be converted to Gd concentration. This method eliminates the need to acquire two datasets, increasing feasibility for clinical use.
