FIG 5. A, Pretreatment angiogram demonstrates the left ICA aneurysm.
B, Phase-contrast MRA obtained after treatment shows occlusion of the aneurysm with no compromise of the parent artery. The polymer does not create any artifact that hinders the application of MRA.
C–E, Corresponding pretreatment T2-weighted turbo spin-echo (C), posttreatment T2-weighted turbo spin-echo (D) and GRE (E) MR images show the hypointense aneurysm. It has an identical appearance before and after treatment that is not possible to appreciate if the aneurysm is patent.
