Due to stringent scan time constraints, flow artifact suppression by moment nulling of the gradients is usually not applied in subtraction first-pass peripheral angiography, since it prolongs echo and repetition times. In this work, a recently proposed subtractionless approach to first-pass peripheral angiography based on dual-echo Dixon imaging is shown to allow an efficient, retrospective elimination of especially high intensity ghosting from pulsatile flow, without requiring changes to the bipolar dual-gradient-echo acquisition employed for chemical shift encoding.
