Aneurysm partially treated with a nitinol stent.

A, Conventional angiogram of a nitinol stent overlying the ostium of a patent aneurysm.

B, CT angiogram.

C, Contrast-enhanced 3D-TOF MR angiographic reformatted planar image (33/3.3/1) parallel to the carotid artery.

D, 3D MR DSA image (11.4/2.2/1). Luminal signal intensity in the parent artery and in the region of the aneurysmal neck are visible but some artifacts are present owing to the nitinol stent. Despite dynamic contrast enhancement, some enhancement is seen within the adjacent jugular vein (arrow).
