AGT and triple-A syndrome: Following 1 week after implantation of osmotic minipumps and continuous AngII infusion, surviving animals showed a stronger signal enhancement from the collagen-binding probe (n = 8, Fig. 3A1–A6), while the administration of iron oxide particles resulted in a larger signal void in animals with subsequent deadly rupture of dissecting AAA (n = 5), resulting from the iron oxide particles, which indicate a pronounced influx of proinflammatory macrophages (also refer to Fig. 3B1–B6).
