Abstract
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.���
