Specifically, the assumptions and limitations of each modality coupled with the varying and often low spatial resolution and their subsequent effect on the hemodynamic metrics was explored. The results of this study demonstrated that non-dimensional parameters, such as OSI, were more robust to varying modalities and spatial resolutions and thus may provide more robust risk or growth and rupture assessments. These results demonstrate a need for further investigation and development of non-dimensional parameters and correlation of such parameters to risk of aneurysm.</p>
