It is known that changes in Abdominal Aortic Aneurysms
(AAA) wall stiffness (WS) can reflect extra-cellular
matrix integrity, a key factor in the pathophysiological
development of AAA and the risk for rupture. Therefore,
our study applied Magnetic Resonance Elastography (MRE)
to determine aortic WS in 10 AAA patients. Our
hypothesis was that there would be no relationship
between aortic WS and AAA diameter and our results
supported the hypothesis with a poor linear correlation
of R2 =0.0051. In the future, a more personalized
approach to AAA management using MRE-derived WS might be
warranted to better assess the risk for rupture.
