MR-guided high intensity focused ultrasound (MRg HIFU) is a novel method of tissue ablation that incorporates high energy focused ultrasound for tissue heating and necrosis within an MR scanner that provides simultaneous stereotactic tissue targeting and thermometry. To date, MRg HIFU has been used primarily to treat uterine fibroids, but many additional applications in the pelvis are in development. This article reviews the basic technology of MRg HIFU, and the use of MRg HIFU to treat uterine fibroids, adenomyosis, and prostate cancer.

Since 1970, the American College of Obstetricians and Gynecologists' Committee on American Indian and Alaska Native Women's Health has partnered with the Indian Health Service and health care facilities serving Native American women to improve quality of care in both rural and urban settings. Needs assessments have included formal surveys, expert panels, consensus conferences, and onsite program reviews. Improved care has been achieved through continuing professional education, recruitment of volunteer obstetrician–gynecologists, advocacy, and close collaboration at the local and national levels. The inclusive and multifaceted approach of this program should provide an effective model for collaborations between specialty societies and health care professionals providing primary care services that can reduce health disparities in underserved populations.
