Molecular Imaging of Experimental Abdominal Aortic Aneurysms
Figure 2
Coronal magnetic resonance maximum intensity projections showing lumen expansion in (a) angiotensin II-induced (AngII) and (b) elastase-induced abdominal aortic aneurysms (AAA). Angiotensin II-induced AAAs appear suddenly (arrowhead) and expand leftward directly above the right renal artery (arrow). Ten additional angiotensin II AAAs are shown at day 28. Elastase-induced AAAs expand slowly. Small region of signal hypointensity is seen at day 3 (triangle) due to a suture in the vessel. Twelve additional elastase AAAs are shown at day 28. The testicular artery is highlighted (arrow). Figure adapted from [77].
