Summary
Magnetic resonance (MR) imaging is safe for women with intrauterine contraceptive devices (IUDs). Studies show IUDs do not move, heat up, or cause artifacts during pelvic MR scans, ensuring patient safety and image quality.
Area of Science:
- Radiology and Imaging
- Medical Devices
- Women's Health
Background:
- Intrauterine contraceptive devices (IUDs) are widely used for birth control.
- Concerns exist regarding the safety of magnetic resonance (MR) imaging in patients with implanted medical devices.
Purpose of the Study:
- To evaluate the safety of MR imaging in women with an intrauterine contraceptive device (IUD).
- To assess potential risks such as IUD motion, heating, and image artifacts during MR procedures.
Main Methods:
- In vitro and in vivo studies were conducted using two common IUD types at 0.35 T and 1.5 T.
- Evaluated IUD motion, temperature changes during specific spin-echo sequences, and artifact generation.
- Retrospective review of pelvic MR images from six women with IUDs.
Main Results:
- No significant IUD motion was observed in the magnetic field.
- IUDs did not exhibit significant heating during commonly used pelvic MR imaging sequences.
- No artifacts were produced by the IUDs in vitro or in vivo, and image quality was not degraded.
Conclusions:
- Magnetic resonance imaging is safe for patients with intrauterine contraceptive devices.
- The presence of an IUD does not compromise the safety or diagnostic quality of pelvic MR imaging.
