Lack of interaction between magnetic resonance imaging and the copper-T380A IUD.
To determine if the CuT380A (ParaGard) IUD is affected by magnetic resonance imaging (MRI), in vitro studies utilizing a CuT380A IUD (ParaGard), a copper-bearing IUD, and a Signa 1.5T HR system were used to evaluate whether the dynamic magnetic forces generated by the MRI resulted in movement, torque, or heat when the IUD was exposed to the magnetic field generated by the MRI. There was no deflection, turning motion (torque), or temperature change when the IUD was exposed to a magnetic field. There appears to be no reason to exclude women with IUDs of the type examined from an MRI system or its environs.
