Focused ultrasound treatment of uterine fibroid tumors: safety and feasibility of a noninvasive thermoablative technique.

Objective: The purpose of this study was to determine the safety and efficacy of focused ultrasound surgery with magnetic resonance imaging guidance for the noninvasive treatment of uterine leiomyomas.

Study Design: Fifty-five women with clinically significant uterine leiomyomas were treated. Pain and complications were assessed prospectively, and posttreatment magnetic resonance imaging was used to measure the treatment effects.
