The primary aim of this study is to establish the practicality of using two novel imaging modalities for the assessment of biomechanical properties of the aorta.
Patients >18 years of age with ability to provide informed consent.
Patients with either symptomatic or asymptomatic AAA as defined by aortic diameter ≥ 1.5x normal diameter.
Patients with non-aneurysmal aortas who require aortic contrast imaging or echocardiography for preoperative planning or other reason.
Patients with contraindication to IV contrast such as allergy or severe kidney dysfunction.
Patients who do not require contrast imaging or echocardiogram as part of their care plan.
Terminally ill patients, and patients with estimated life expectancy of ≤ 6 months.
Patients unable to tolerate magnetic resonance imaging.

ECG-gated MRA
DeviceImaging
ECHO Imaging
Imaging taken of the aneurysm, locating peak wall stress and measuring percent of strain per seconds.
ECG-gated MRA Imaging
The MRA imaging will be taken with the ECG-gating to synchronize the timing of the image acquisition with cardiac motion. This will allow for more accurate measurement of vessel diameter measured in mm (millimeters) and reported in percent change from baseline.
