Safety of intrauterine devices in MRI

Safety of intrauterine devices in MRI

Standard IUDs (copper/gold) can be considered as conditional for MR safety at 1.5 T and 3.0 T, demonstrating at wbSAR up to 4W/kg and a magnetic field gradient of up to 40T/m with minimal imaging artifacts. The stainless steel IUD, however, induces unacceptable artifacts and is potentially harmful to patients during MRI due to high magnetic dislocation forces and torque (MR unsafe).

Adolescents and Long-Acting Reversible Contraception: Implants and Intrauterine Devices

Adolescents and Long-Acting Reversible Contraception: Implants and Intrauterine Devices

Because adolescents are at higher risk of sexually transmitted infections (STIs), obstetrician–gynecologists should continue to follow standard guidelines for STI screening. They should advise adolescents who choose LARC methods to use male or female condoms consistently (dual method use) to decrease the risk of STIs, including human immunodeficiency virus (HIV). Obstetrician–gynecologists should counsel all sexually active adolescents who do not seek pregnancy on the range of reversible contraceptive methods, including LARC, and should help make these contraceptives readily accessible to them.

Recent intrauterine device use and the risk of precancerous cervical lesions and cervical cancer

Recent intrauterine device use and the risk of precancerous cervical lesions and cervical cancer

Recent levonorgestrel-IUD use may be associated with CIN2, a lesion with a high rate of regression, but not CIN3, which is considered a true pre-cancerous lesion. The observed association between levonorgestrel-IUDs and CIN2+ was modest but warrants further investigation. It may have clinical importance for contraceptive counseling if this finding is shown to be consistent across other studies and other populations.

Factors associated with low-lying intrauterine devices: a cross-sectional ultrasound study in a cohort of African-American women

Factors associated with low-lying intrauterine devices: a cross-sectional ultrasound study in a cohort of African-American women

Women who are obese may benefit from additional counseling and closer follow-up after IUD placement. Future research is warranted to investigate IUD placement and possible IUD migration among women who are obese.

Perforation risk and intra-uterine devices: results of the EURAS-IUD 5-year extension study

Perforation risk and intra-uterine devices: results of the EURAS-IUD 5-year extension study

The overall perforation rate was 2.1 per 1000 insertions for LNG-IUS users 1.6 per 1000 insertions for copper-IUD users……. LNG-IUS users had a borderline higher risk of perforation compared with copper-IUD users.
Forty-five (58%) of the 77 perforations were associated with suspected risk factors……
Breastfeeding…… and time since delivery remained significant risk factors in perforations detected after 12 months.
No perforations resulted in serious injury to intra-abdominal or pelvic structures.

Chronic Systemic Toxicity Study of Copper Intrauterine Devices in Female Wistar Rats

Chronic Systemic Toxicity Study of Copper Intrauterine Devices in Female Wistar Rats

The aim of this study was to evaluate the chronic systemic and local toxicity of a copper intrauterine device in a rat model. These results obtained at different dosages and long-term implantation provide solid data confirming the safety of long-term use of Cu-IUDs. However, the elevated leucocyte levels found in this study warrant further investigation.

Includes lots of references to other studies.
