Can software be developed to automatically aid in the measurement of abdominal aortic aneurysms, and is there a way to predict future rupture or growth of abdominal aortic aneurysms.
Hypothesis: ECG-gated multidetector CT and ECG-gated Dual Source CT can be used to create multiple volumetric datasets of the abdominal aorta over the time period of the cardiac cycle, allowing for direct and regional calculations of abdominal aortic distensibility over the entire volume of the abdominal aorta, providing insight into risk of abdominal aortic aneurysm rupture and early large vessel stiffness.

In year one, this data will be used to develop pulsatility software and test robustness.
Time frame: First Year
In year two, the time-resolved CT angiographic datasets from each patient will be analyzed to determine peak AAA pulsatility and peak AAA relative pulsatility (to cross-sectional area within the aneurysm).
Time frame: Year Two
