MR velocimetry reproducibility was mesured in a cohort of 88 subjects with untreated aneurysms that were evaluated repeatedly over periods of time as long as 7 years. Reproducibility was also measured in exact replicas of the complex geometries of a subset of these subjects. Good agreement was found between experimental and computational flow measurements. In vivo studies were found to be reproducible with an error of measurement of 10%.
