| Outline of Final Research Achievements |
We developed the new CFD analysis method using the 4D-PC-MRA flow data. Our CFD results were compared to the flow data by 4D-PC-MRA. Five unruptured cerebral aneurysms were included in this study. 3D-computational meshes were created from 3D-DSA images and CFD simulations were performed for two conditions: I= patient-specific inflow measured by 3D-PC MRA, II= patient-specific inflow and outflow measured by 3D-PC MRA. Difference in flow vector between CFD and PC-MRA was calculated at parent artery, aneurysm and distal arteries. The flow features such as vector map were similar between CFD and 4D-PC-MRA. There are no significant difference between condition I and II, but aneurysm showed statistically large flow difference compared to parent artery and distal arteries. Further study is needed to combine whole flow data of 4D-PC-MRA for CFD simulations.
