The measurement of arterial stiffness has long been a reliable method of determining the severity and risk involved with many cardiovascular diseases . Magnetic resonance elastography (MRE), a non-invasive MRI-based technique, has recently been applied to measure aortic stiffness . The aim of this study is to determine MRE-derived shear stiffness (μMRE) of the abdominal aorta over the cardiac cycle.
This preliminary study demonstrated the feasibility of determining aortic stiffness values during the cardiac cycle and also showed that aortic stiffness values varied during the cardiac cycle. The stiffness values are lower during the diastolic phases when compared to systolic phases. However, additional data is warranted to establish the stiffness values of the aorta during the cardiac cycle.
