Reproducibility of the computational fluid dynamic analysis of a cerebral aneurysm monitored over a decade
Computational fluid dynamics (CFD) simulations are increasingly utilised to evaluate intracranial aneurysm (IA) haemodynamics to aid in the prediction of morphological changes and rupture risk. However, these models vary and differences in published results warrant the investigation of IA-CFD reproducibility.
This data set supports the study that aimed to explore sources of intra-team variability and determine its impact on the aneurysm morphology and CFD parameters. A team of four operators were given six sets of magnetic resonance angiography data spanning a decade from one patient with a middle cerebral aneurysm. All operators were given the same protocol and software for model reconstruction and numerical analysis. The morphology and haemodynamics of the operator models were then compared.
This is data collected for the morphology and haemodynamics at systole of the patient-specific aneurysm at 6-time points for all 4 operators in this study. Patient imaging data (MRI or CT scans) were not provided due to ethics obligations.
