  		Fig. 1. —Digital radiographic angiogram shows exact delineation of stenoses inside stents. Stents are shown from left to right control, Strecker Tantalum (Boston Scientific Europe, Paris, France), Strecker Nitinol (Boston Scientific Europe), ZA-Stent (Cook, Moenchengladbach, Germany), Symphony (Boston Scientific Europe), Easy Wallstent (Boston Scientific Europe), Perflex (Cordis, Miami, FL), and Palmaz P394 (Cordis).

  		Fig. 2. —Multidetector CT angiogram shows dependency of stenosis delineation on stent type. Stents appear in same order as in Figure 1: control, Strecker Tantalum (Boston Scientific Europe, Paris, France), Strecker Nitinol (Boston Scientific Europe), ZA-Stent (Cook, Moenchengladbach, Germany), Symphony (Boston Scientific Europe), Easy Wallstent (Boston Scientific Europe), Perflex (Cordis, Miami, FL), and Palmaz P394 (Cordis). Complete obscurity of stenosis is caused by Strecker tantalum stent. In other stents (steel, nitinol, and cobalt-based alloy), stenoses are delineated.

  		Fig. 3. —MR angiogram shows dependency of stenosis delineation on stent types. Stents appear in same order as in Figure 1: control, Strecker Tantalum (Boston Scientific Europe, Paris, France), Strecker Nitinol (Boston Scientific Europe), ZA-Stent (Cook, Moenchengladbach, Germany), Symphony (Boston Scientific Europe), Easy Wallstent (Boston Scientific Europe), Perflex (Cordis, Miami, FL), and Palmaz P394 (Cordis). Only minor artifacts are caused by Strecker tantalum stent. Good stenosis delineation is shown for Strecker nitinol, ZA-Stent, and Easy Wallstent. Limitations in stenoses delineation are caused by signal decrease inside Symphony and Perflex stents. Stenosis is not visible in Palmaz P394 stent.
