Intrauterine contraceptive devices (IUD) may be made from nonmetallic materials (e.g., plastic) or a combination of nonmetallic and metallic materials. Copper is typically the metal used in an …

In view of our results, copper/gold/silver containing IUDs appear to be clinically safe with MRI effects being significantly less than earth’s gravitational force, in contrast to the stainless steel …

Many studies have shown that common hormonal and metallic intrauterine devices are safe to scan with MR imaging; however, the stainless-steel ring IUD (often termed the “Chinese” IUD) …

The only IUDs deemed MR Unsafe are stainless-steel ring-shaped devices distributed exclusively in China between 1988 and 2000. Because millions of such IUDs were implanted, a …

Feb 3, 2025 · MRI. The MRI compatibility of intrauterine contraceptive devices may be of concern to women undergoing MRI examinations. Generally speaking, stainless steel devices are …

Oct 9, 2018 · Standard IUDs (copper/gold) can be considered as conditional for MR safety at 1.5 T and 3.0 T, demonstrating at wbSAR up to 4W/kg and a magnetic field gradient of up to …

Testing conducted to determine MRI issues for the copper IUDs indicated that these objects are safe for patients in the MR environment using MR systems operating at 1.5-Tesla or less. This …

Based on these results, all IUDs tested are both safe and compatible with MRI at 3T and 7T in the animal model. We believe, therefore, that these IUDs would also be safe in humans. This …
