What is MRI-guided Focused Ultrasound (MRg-FUS)?
MRg-FUS is only available at a small number of medical facilities in the United States. It combines the imaging capability of magnetic resonance imaging (MRI) to target tumors (ex. fibroids) inside the body with a special ultrasound unit capable of delivering a beam of focused ultrasound energy. This energy is used to destroy the tumor while completely sparing the adjacent normal tissue. During the treatment session, MRI images allow the treating physician to “see” inside the body and monitor the treated tumor in a completely noninvasive manner. How is the procedure done for uterine fibroids? Immediately prior to the procedure, the woman has a catheter inserted in an arm vein and a bladder catheter placed.
