Is MRI safe with an IUD, implants, menstruation, or pregnancy?

Most modern copper and hormonal IUDs are considered MRI-safe or MRI-conditional, meaning MRI can be performed with certain manufacturer conditions. The key is knowing the exact device and model, so it helps to bring any IUD/implant card or documentation and tell the MRI team what you have so they can confirm compatibility and scanner settings.

Having your period usually doesn’t affect MRI safety, and imaging can typically be done regardless of cycle timing unless your specific exam has timing-dependent goals. In pregnancy, MRI without gadolinium contrast is generally considered safe when it’s needed to answer an important clinical question, while gadolinium is usually avoided unless the expected benefit clearly outweighs potential risk. If you’re unsure about your device, possible pregnancy, or whether contrast is being planned, our team can help you clarify what’s safest and most appropriate and coordinate next steps.
