Reproducibility of hemodynamic simulations of cerebral aneurysms across imaging modalities 3DRA and CTA: Geometric and hemodynamic data

The dataset contains values for geometric and hemodynamic variables that were derived from the CFD simulations. The variables are defined as follows (TA: time-averaged; PS: peak systole; ED: end diastole):

• A_N: Aneurysm neck area
• V_A: Aneurysm volume
• Q_P: TA flow rate in the parent vessel just proximal to the aneurysm
• Q_A: TA flow rate into the aneurysm
• NQ_A: Q_A / Q_P
• WSS_P: Average TA WSS on the wall of a parent vessel segment just proximal to the aneurysm
• WSS_A: Average TA WSS on the aneurysm wall
• NWSS_A: WSS_A / WSS_P
• LWSS_A: Portion of the aneurysm wall with WSS < 0.4 Pa at ED
• MWSS_A: Maximum WSS on the aneurysm wall at PS
• 90WSS_A: 90th percentile value of the WSS on the aneurysm wall at PS
• N90WSS_A: 90WSS_A normalized by the average WSS on the aneurysm wall at PS See github.com/ajgeers/3dracta for an analysis of the data.
