Background:
Concerns about women who have implanted or in situ medical devices undergoing magnetic resonance (MR) imaging engender the need for testing. Prior testing of the Copper T 380A intrauterine device (IUD) has been done using MR systems of 1.5 T or less. This study was performed to test this IUD in a MR system of 3.0 T.
Materials And Methods:
In vitro safety testing was done via the Copper T 380A IUD using a GE Signa LX 3.0-T MR system. Variables tested included deflection, torque, heating and artifact.
Results:
No significant deflection, torque, heating or artifact was found in this in vitro testing model.
Conclusion:
The outcomes measured revealed no safety concerns for the use of the Copper T 380A IUD at 3.0 T under the conditions of testing. This finding is compatible with the new standards adopted by the American Society for Testing and Materials and the Food and Drug Administration (FDA), with a rating of "MR Conditional."
