3.0 T vs. 1.5 T MR angiography: In vitro comparison of intravascular stent artifacts

Abstract

Assessment of the stent lumen in iliac artery stents in a phantom model is not compromised by imaging at 3 T compared to 1.5 T. The signal gain inside the stented part of the vessel lumen at higher field compensates for the higher degree of stent artifacts seen in stents made of steel or cobalt.
