Purpose: To evaluate the MR compatibility of commonly used metallic implants like intracranial aneurysm clips, coronary artery stents and iliac stents with respect to magnetic attraction forces and radio frequency related heating at 3.0 Tesla . Methods: 9 commercially available aneurysm clips designed for permanent placement in intracranial aneurysms, 19 commonly used coronary artery stents and 20 wildly used iliac artery stents of different size and materials were studied in a 3.0 T system (Intera, Philips Medical Systems). Each metallic implant was evaluated for.: 1. magnetic deflection forces (translational m…
