Intraluminal signal intensity of iliac artery stents investigated by contrast-enhanced three-dimensional MR angiography

Comput Med Imaging Graph. 1998 Jan-Feb;22(1):9-12. doi: 10.1016/s0895-6111(97)00040-2.


The purpose of this study is to investigate the intraluminal signal of iliac artery stents by contrast-enhanced three-dimensional magnetic resonance (MR) angiography with a short echo time. Ten patients with iliac arterial diseases treated by intravascular metallic stent placement were examined with a 1.5 T MR imager. Gadolinium-enhanced MR angiography depicted the intraluminal signal in Strecker stent, but not in the Wallstent and Palmaz stent. Strecker stent made of nonferromagnetic tantalum was the best-suited stent for use with contrast-enhanced MR angiography.
