A, MIP image of MRA with injection from the left arm shows reflux of contrast in both jugular veins and the epidural venous plexus with poor opacification of the arterial system. B, In the same patient, the MIP image of MRA repeated after 4 days with injection from the right arm shows adequate opacification of the arterial system without venous reflux. Also note the ectatic arch of the aorta.
