Abstract
The authors developed ABI alloy, which mechanically resembles stainless ste el 316. The main elements of ABI alloy are palladium and silver. Magnetic r esonance (MR) images and radiographs of ABI alloy and stainless steel 316 s tent models and of nitinol, tantalum, and Elgiloy stents were compared. ABI alloy showed the least MR imaging artifacts and was more radiopaque than s tainless steel 316. ABI alloy has the potential to replace stainless steel 316 for construction of balloon-expandable MR imaging-compatible stents.
