Key result
MR elastography demonstrates feasibility for noninvasive assessment of abdominal aortic stiffness.
Why the study?
The feasibility of using MR elastography for noninvasive evaluation of in vivo aortic wall stiffness was not established.
Is MR elastography feasible for evaluating the stiffness of the in vivo aortic wall?
Population
Five volunteers aged 22-40 years with BMI 21.5-25.2 kg/m2 and a gel phantom with embedded porcine aorta
Comparison

Is MR elastography feasible for evaluating the stiffness of the in vivo aortic wall?
MR elastography is a feasible noninvasive technique for assessing the stiffness of the abdominal aorta during diastole.
Xu et al. (2013) reported an observational. MR elastography (MRE) was evaluated on Feasibility of visualizing wave propagation. MR elastography successfully visualized wave propagation within the abdominal aorta during diastole in 5 volunteers, demonstrating feasibility for noninvasive stiffness assessment.
