Dynamic contrast enhanced MRI for characterizing perfusion in the myocardium is becoming a more robust and useful clinical tool. Methods for ungated acquisitions and retrospective self-gating were recently introduced. Such ungated imaging could be valuable whenever ECG-gating is poor, and in particular in patients with arrhythmias. Here we compare a self-gated perfusion acquisition directly to a gated acquisition in subjects in sinus rhythm, to determine how well quantitative perfusion values in ml/min/g can be obtained with the self-gated approach.
