Noncontrast enhanced (NC)-MRA with inflow inversion recovery technique, IFIR FSE can be obtained for the evaluation of the arteries from the aortic arch to the skull base using peripheral pulse gating at 3T in combined use of compressed sensing and parallel imaging ARC. This technique may be used as a screening method covering the wide areas of the arteries within an acceptable short imaging time and image quality in the patients with cerebral vascular diseases. In those cases, robust imaging parameters have to be applied for stable NC-MRAs.
