FIG 4. Model 3, small-necked giant lateral aneurysm. Voxel size, 0.16 mm.

A, The true shape of the aneurysm was not visualized on the 3D reconstruction.

B, The 14-second rotation with a bolus injection reveals only the distal aneurysmal shell.

C, In the 14-second rotation, the proximal wall of the aneurysm is not clearly delineated, even after the administration of contrast material at a rate of 5 mL/s.
