Reporting Groups
  Description
HIFU Treated Women indicated for total abdominal hysterectomy underwent a single Magnetic Resonance guided-High Intensity Focused Ultrasound (MR-HIFU) session for uterine fibroid ablation prior to surgery. Subjects were followed up until the date of hysterectomy, or for 30 days if hysterectomy was declined.
