MRI scanners and the stapes prosthesis. Nitinol (nickel-titanium alloy) is a shape-memory metal alloy that has been used in medical applications for years. Stapes implants are available in many sizes, materials, and designs, such as the Big Easy Piston and the Roberson Stapes Prosthesis. The unique shape memory zone ensures complete (360) gentle closure around the incus. The medical device SMART STAPES PISTON .5 is realized by GYRUS ACMI INC.

OBJECTIVE: To assess the magnetic resonance imaging (MRI) safety of titanium middle ear prostheses at 3.0 tesla (T). Otologic Implants, Micromedics, Inc. (Eagan, MN) MRI testing at 3-Tesla was conducted on the following products from Micromedics, Inc: Stainless Steel Vent Tube & Stainless Steel Wire Because of the size of the metallic mass associated with this particular product, the MRI test findings (MR Conditional 6, 3-Tesla or less) apply to all of the products listed below (Micromedics, Inc., Eagan, MN): VT-0205-, Fluoroplastic with stainless steel wire VT-0702-, Silicone with stainless steel wire VT-1402-, Stainless Steel with stainless steel wire VT-1412-, Titanium with stainless steel wire VT-1505-, Polyethylene with stainless steel wire Otologic Implants, Grace Medical (Memphis, TN). It is hypothesized that some metal stapes prostheses may be exposed to powerful MRI scanners without leading to potential adversities for patients.

Around like i did ask for proof of adverse events production of future stapes stapes bone others. MRI is based on the principles of nuclear magnetic resonance, a spectroscopic technique to obtain As MRI scanners become more powerful, the possibility for stapes prosthesis displacement due to ferromagnetic forces increases. The author concludes that patients with all types of stapes prostheses, with the exception of several mismanufactured lots of McGee pistons implanted between 1987-1989, can safely undergo MRI scanning up to 9.4T.
