LACK OF INTERACTION BETWEEN MAGNETIC-RESONANCE-IMAGING AND THE COPPER-T380A IUD

To determine if the CuT380A (ParaGard(R)) IUD is affected by magnetic resonance imaging (MRI), in vitro studies utilizing a CuT380A IUD (Par aGard(R)), a copper-bearing IUD, and a Signa 1.5T HR system were used to evaluate whether the dynamic magnetic forces generated by the MRI r esulted in movement, torque, or heat when the IUD was exposed to the m agnetic field generated by the MRI. There was no deflection, turning m otion (torque), or temperature change when the IUD was exposed to a ma gnetic field. There appears to be no reason to exclude women with IUDs of the type examined from an MRI system or its environs. (C) 1997 Els evier Science Inc.
