We present a novel contrast mechanism for creating MR angiograms on the basis of ghost artifacts originating from pulsatile arterial flow. The method, which we call Ghost MRA, is amenable to numerous pulse sequences and does not require cardiac synchronization or image subtraction to suppress background tissue.
