Medical ultrasound uses high-frequency sound waves to produce images of internal structures. Unlike an X-ray, it does not use ionizing radiation.
This educational information does not replace guidance from a professional or confirm which test or treatment is appropriate for any person.
Ultrasound essentials
The equipment sends sound waves and records their echoes to produce images of structures inside the body.
Ultrasound does not use the ionizing radiation used in conventional X-ray imaging.
The type of ultrasound and the area being evaluated determine whether specific instructions apply before the visit.
