Magnetic Resonance-Guided High-Intensity Focused Ultrasound for Treatment of Women with Symptomatic Uterine Fibroids


Ontario Health Technology Advisory Committee Recommendations

  • Based on the current available evidence, the Ontario Health Technology Advisory Committee recommends that magnetic resonance–guided high-intensity focused ultrasound be considered as one option in the treatment of symptomatic uterine fibroids in women who are unresponsive to medical therapy.

Uterine fibroids are common noncancerous growths in the uterus. Many fibroids cause no problems, but in some cases women experience problems such as pain, heavy menstrual bleeding, bladder problems, and infertility.

Each year in Ontario, thousands of women seek medical attention for symptoms related to fibroids. Medication often helps. Other options include surgery (to remove the fibroids or the entire uterus) or a procedure called uterine artery embolization, which destroys fibroids by blocking their blood supply.


Health Quality Ontario Reviews Magnetic Resonance-Guided High-Intensity Focused Ultrasound for the Treatment of Uterine Fibroids

Many women with uterine fibroids want to avoid surgery, especially if they want to have children in the future. A non-invasive alternative is magnetic resonance-guided high-intensity focused ultrasound. This treatment uses ultrasound waves to heat and destroy the fibroids.
