Fig. 1C. —77-year-old man with aortic nitinol stent-graft. MR angiogram
obtained 24 hr after A reveals increased volume of endoleak (solid
arrow [area outlined in white]) at same level as that shown in A
and B. This method was used to determine the area on every scan with
contrast extravasation into aneurysmal sac for calculating endoleak volume.
Note wraparound ghosting artifact (open arrow) in slice
