Morphological and Biomechanical Differences in the Elastase and AngII apoE^−/− Rodent Models of Abdominal Aortic Aneurysms

Figure 1

AAA diameter and volume increases over 28 days. Representative B-mode images (maximum aortic cross-section), aortic volumes (days 0 and 28), and longitudinal measurements of effective maximum diameter ((a), (b)) and volume/length ((c), (d)) in high-concentration-elastase rats ((a), (c)) and AngII apoE^−/− mice ((b), (d)). Arrows point to abdominal aorta in cross-section. Volume segmentations: 30 mm in rats and 15 mm in mice (0.19 mm step size). Scale bars: 2 mm (a), 1 mm (b), 10 mm (c), and 5 mm (d).
