Why the study?
Does nontriggered MRI quantification of aortic pulse-wave velocity accurately measure arterial stiffness compared to retrospectively EKG-gated PC-MRI in healthy subjects?
Population
23 healthy subjects (ages 20-70 years) without symptoms or prior history of cardiovascular events.
Comparison

May support simpler aortic PWV assessment in healthy subjects; leaves open validation in patients.
Does nontriggered MRI quantification of aortic pulse-wave velocity accurately measure arterial stiffness compared to retrospectively EKG-gated PC-MRI in healthy subjects?
A novel nontriggered MRI technique using velocity-encoded projections accurately quantifies aortic pulse-wave velocity with less than 4% RMS difference compared to standard EKG-gated PC-MRI.
