Fig 3. A, Axial source image at the level of 2 cobalt clips demonstrates significant artifacts that obscure the surrounding brain and vessels. Wider windows were used to minimize artifacts but resulted in poor vessel contrast differentiation. B, Axial source image through a series of 3 titanium aneurysm clips, with a fourth clip partially imaged, demonstrates minimal artifacts related to the titanium, and the parent vessel can easily be seen (arrow) with no evidence of residual aneurysm. C, 3D volume rendering demonstrates the 4 titanium clips and adjacent vessels without significant degradation by artifacts. D, Catheter angiogram demonstrates the original aneurysm before clip reconstruction.
