Intracranial Aneurysm Neck Size Overestimation with 3D Rotational Angiography: The Impact on Intra-Aneurysmal Hemodynamics Simulated with Computational Fluid Dynamics

摘要

3DRA is considered the reference standard for the assessment of intracranial aneurysm morphology. However, it has been shown that 3DRA may overestimate neck size compared with 2D DSA. The purpose of this study was to determine the impact of neck size overestimation with 3DRA on intra-aneurysmal hemodynamics.
