A, Selective DSA of the right internal carotid artery before treatment reveals a giant carotid-ophthalmic aneurysm. B, Selective DSA after embolization demonstrates complete occlusion of the aneurysm but with slightly reduced coil compaction near the neck. C and D, Follow-up 3D TOF MRA source image (C) and MIP reconstruction (D) obtained at 8 months after treatment reveal residual patency, but clear definition of the (type 2) remnant is compromised by saturation and methemoglobin artifact. E and F, Clearer depiction of the residual aneurysm is achieved on CE-MRA source images (E) and MIP reconstruction (F).
