Fig 3. Giant aneurysm with no neck, incompletely treated with coils. A large residual flow is present inside the aneurysmal sac.
A, 3D TOF transverse source image shows that the signal intensity inside the treated giant aneurysm (arrow) is degraded. The limits of residual flow are not clear between the strong flow signal intensity, the intermediate slow or turbulent flow signal intensity, and the intermediate blood clot signal intensity.
B and C, CE-MRA source image and MIP anterior projection show that the remnant aneurysm is clearly defined and the visualization of the carotid branch conformation with the aneurysm is better.
D, DSA right carotid angiogram, anterior view, shows large residual aneurysm.
