Key result
4D flow MRI of the aorta in healthy adults showed limited differences between males and females, but a strong negative relationship with age for almost all flow-related parameters and segments.
Why the study?
A limited number of studies have established normal values for aortic blood flow characterization by 4D flow MRI to aid early recognition of abnormal flow.
Population
191 healthy adults completing the full study protocol out of 212 included volunteers
Comparison
Sex-specific and age-dependent groups
Design
Cross-sectional cohort study

Sex-specific aortic flow references from 4D MRI may aid abnormality detection; extends limited normative data but leaves clinical utility open.
Cross-Sectional (n=191)
This study establishes sex-specific and age-dependent reference values for aortic flow parameters using 4D flow MRI, demonstrating limited sex differences but a strong negative correlation with age.
Ramaekers et al. (2024) conducted a cross-sectional in Healthy adults (n=191). Age and Sex was evaluated on Quantitative values for velocity, vorticity, helicity, and wall shear stress in the aorta. 4D flow MRI of the aorta in healthy adults showed limited differences between males and females, but a strong negative relationship with age for almost all flow-related parameters and segments.
