Renal magnetic resonance angiography: an update.
Recent developments in renal magnetic resonance angiography have led to a significant improvement in the technical success rate and diagnostic accuracy of the methods. Specifically, three-dimensional contrast-enhanced magnetic resonance angiography methods have been shown to provide a more reliable depiction of renal artery morphology than older techniques. In addition, recent work has shown that variations of magnetic resonance angiography methods have several important attributes that may make it feasible to demonstrate the hemodynamic significance of a renal artery stenosis. Recent data show that magnetic resonance angiography methods may be used to predict patient outcome in response to revascularization therapy.
