Purpose: To assess the feasibility of MR-guided endovascular interventions at 3 T, using catheters marked with iron particles. Materials and Methods: Different interventional procedures were performed in 12 pigs as follows: In 4 animals surgically induced stenosis of the femoral arteries were dilated using a balloon catheter filled with Gd-DTPA solution. In 4 pigs nitinol stents were placed in the iliac arteries. In the remaining 4 animals, segmental renal arteries were embolized with 0.5ml butylcyanoacrylate (Histoacryl, B. Braun, Germany), mixed with lipoidol and iron particles. A non-metallic guide wire and n…
