title: Blood pool MR angiography of aortic stent-graft endoleak.
abstract: OBJECTIVE
  The purpose of our research was to investigate the value of a blood pool contrast agent in detecting endoleaks on MR angiography after endoluminal stent-graft repair of infrarenal aortic aneurysms.
  
  
  CONCLUSIONS
  Blood pool MR angiography using Ferumoxytol reveals more aortic stent-graft endoleaks than does CT angiography and depicts more endoleaks 24 hr after administration than during the immediate arterial phase because of a 50-fold increase in the volume of enhancement in the aneurysmal sac outside the stent-graft.
