According to the literature mentioned below MR-examinations in a strength of up to 3.0 Tesla in women who have a copper intrauterine device for contraception (IUD) in place, does not influence neither the results of the MR-examination nor the functional efficacy of the IUD.
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 3.0 Tesla or less. This includes all Copper IUDs.
An artifact may be seen for the metallic component of the IUD; however, the extent of this artifact is relatively small because of the low magnetic susceptibility of copper.
