Segmentation of Lumen and Outer wall of Abdominal Aortic Aneurysms from 3D Black-Blood MRI with a Registration Based Geodesic Active Contour Model

Abdominal Aortic Aneurysm (AAA) is the direct cause of more than 15,000 deaths each year in the United States and is the cause of 1.3% of all deaths among men aged 65-85 years in developed countries (Sakalihasan et  al., 2005; Upchurch and Schaub, 2006). Most AAAs are not detected because AAA disease is usually asymptomatic; patients generally exhibit no major symptoms until the aneurysm ruptures (Cornuz et al., 2004). As the abdominal aorta is the largest blood vessel in the body, rupture can lead to massiv e internal bleeding and mortality rates approach 90% if rupture occurs outside of the hospital setting (Mozaffarian et al., 2016).
