Predicting Rupture of AAA by Anatomic and Hemodynamic Markers

Predicting Rupture of Abdominal Aortic Aneurysm (AAA) by Anatomic and Hemodynamic Markers From In-vivo and In-vitro Imaging

The purpose of the study is to investigate imaging findings, which can help us to predict factors contributing to abdominal aortic aneurysm growth and rupture.

Inclusion Criteria:

• Individuals between 18 and 80 years old receiving medical care at University of Minnesota Medical Center who have a normal aorta CTA within the previous year
• Or patients with known AAA with growth rate of 0-0.2 cm/year
• Or patients with known AAA with growth rate of greater than 0.5 cm/year.

Exclusion Criteria:

• Subjects with ferromagnetic implants
• Penile implant
• Hip replacement
• History of shrapnel or shot gun injury
• Body mass index ≥ 30
• Cardiac pacemakers
• Severe claustrophobia
• Large tattoos on the torso
