The purpose of this study was to test the feasibility of real‐time magnetic resonance (MR) guidance of iliac artery stent placement. Radial scanning together with the sliding window reconstruction technique was implemented on a 1.5 T magnet, yielding a frame rate of 20 images per second. Seven prototype nitinol ZA stents were deployed in iliac arteries of living pigs under MR control. All stents were well visualized on the radial MR images, allowing depiction of the mounted stents as well as stent deployment without anatomy‐obscuring artifacts. Stent placement was sucessful in all cases and took 6 minutes on average. The position of the stents was correctly visualized by real‐time radial MR scanning, as proved by digital subtraction X‐ray angiography. Combined radial scanning and the sliding window reconstruction technique allow real‐time MR‐guided stent placement in iliac arteries. J. Magn. Reson. Imaging 2000;12:616–622. © 2000 Wiley‐Liss, Inc.
