Magnetic Resonance Elastography in Patients With Abdominal Aortic Aneurysms

Brief Summary

The main objective of this study is to utilize Magnetic Resonance Elastography (MRE) to determine tissue stiffness of abdominal aortic aneurysms (AAA). For patients with AAA, MRE is a more sensitive and superior method of determining the risk for rupture of AAA based on stiffness estimates when compared to the current, crude method of assessing risk based on measurement of the diameter of the aneurysm. The investigators will also validate the stiffness estimates against gold standard i.e. mechanical testing and histopathology only AAA patients undergoing AAA surgery.
