## Abstract ## Purpose To validate magnetic resonance imaging (MRI) assessment of aortic pulse wave velocity (PWV~MRI~) with PWV determined from invasive intra‐aortic pressure measurements (PWV~INV~) and to test the reproducibility of the measurement by MRI. ## Materials and Methods PWV~MRI~ was

## Abstract ## Purpose: To study age‐related change in aortic stiffness in patients with Marfan syndrome (MFS) versus healthy volunteers using velocity‐encoded (VE) MRI. ## Materials and Methods: Twenty‐five MFS patients (age range, 18–63 years; mean age 36 ± 14 years, 13 men) and 25 age‐/gender
By using a comprehensive MRI-approach in patients with Marfan syndrome, increased regional pulse wave velocity in the ascending aorta can predict in 42% of the cases aortic luminal growth in the ascending aorta, while normal PWV can predict in 89% absence of luminal growth.
