1 Time-resolved magnetic resonance angiography as a noninvasive method to characterize endoleaks: initial results compared with conventional angiography  Robert A Lookstein, MD, Jeffrey Goldman, MD, Lev Pukin, MD, Michael L Marin, MD  Journal of Vascular Surgery  Volume 39, Issue 1, Pages (January 2004) DOI: /j.jvs

2 Fig 1 A, Multidetector computed tomographic angiogram of a patient with a bifurcated aortic stent graft and a large endoleak seen to the left side of the graft. Shaded surface display and maximum intensity projection demonstrate the endoleak to be in continuity with the inferior mesenteric artery. The leak is in proximity to the proximal attachment site of the device. B, Contrast-enhanced magnetic resonance angiography in anteroposterior and lateral projections demonstrate the endoleak channel. C, Time-resolved magnetic resonance angiography imaged in the coronal plane demonstrates that this patient with a bifurcated abdominal endograft has a proximal type 1 endoleak with outflow via the inferior mesenteric artery. D, Conventional digital subtraction angiogram confirms the diagnosis of the proximal type. Journal of Vascular Surgery  , 27-33DOI: ( /j.jvs )
