Fig 2.

Model 2, wide-necked aneurysm in the MCA bifurcation and AcoA. Voxel size, 0.25 mm.

A, The 5-second rotation with continuous flow shows filling defects in both aneurysms (arrows).

B, The 8-second rotation with continuous flow shows a slight defect in the MCA aneurysm (arrow).

C, Accurate visualization of the aneurysm is achieved in the 8-second rotation with the bolus injection.

D, The 14-second rotation with continuous flow has higher plasticity, but it does not provide any additional information about the geometry of the aneurysm.
