Metallic artifacts of coronary and iliac arteries stents in mr angiography and contrast-enhanced CT

      Abstract

      Metallic artifacts of intravascular stents were assessed with MR angiography and contrast-enhanced spiral CT. Stainless steel stent showed less metal artifact than tantalum stent in CT. Metallic artifact in coronary and iliac arteries treated with tantalum stent was not remarkable in MR angiography. Contrast-enhanced CT might be preferable to assess patency of arteries treated with stainless steel stent, while MR angiography was useful in depicting intraluminal signal in tantalum stent.
