Ablation: Non-surgical destruction of a body part or tissue.

ExAblate™: The commercial name for the system that provides non-invasive treatment using Magnetic Resonance guided Focused Ultrasound technology. It received FDA approval for treatment of uterine fibroids in October 2004 .

Hysterectomy: Surgical removal of the uterus.

Magnetic Resonance guided Focused Ultrasound: A non-invasive outpatient, procedure that uses high intensity focused ultrasound waves to ablate (destroy) tissue in combination with Magnetic Resonance Imaging (MRI), which guides and monitors the treatment.

MRgFUS: Magnetic Resonance guided Focused Ultrasound.

Magnetic Resonance Imaging (MRI): A non-invasive imaging method using magnetic fields and radio waves to create images of the body.

Myomectomy: Surgical excision of the tumor, leaving the healthy areas of the uterus in place.

Hormonal therapy: A drug treatment used to treat some fibroids that causes
fibroid shrinkage.

Symptomatic uterine fibroids: Benign (non-cancerous) masses located in the uterus that cause any of the following symptoms, including heavy bleeding or painful periods; bleeding between periods; feeling “full” in the lower abdomen; frequent urination (resulting from a fibroid pressing on the bladder); bowel symptoms; pain during sex or lower back pain

Thermal ablation: Destruction of a body part or tissue using heat.

Uterine artery embolisation (UAE): Blocking the blood vessels that supply the tumor by injecting small particles into the arteries feeding the uterus.

Uterine fibroids: Benign (non-cancerous) masses located in the uterus or in the uterine wall.

Ultrasound: High-frequency sound waves (not audible to the human ear).
