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

Figure 4

Gross dissection of AAAs shows shape of AAAs detected by B-mode images. End-of-study dissection images of AAAs in situ and short-axis B-mode images at day 28 from a high-concentration-elastase rat ((a), (c)) and an AngII apoE^−/− mouse ((b), (d)). B-mode images taken at the approximate anatomical locations marked by green dashed lines ((a) and (b)). White dashed lines indicate locations selected for histology. Scale bars: 5 mm (a); 2 mm (b); 2 mm (c); and 1 mm (d).
