An ultrasound examination is a radiology procedure that utilizes high-frequency sound waves to produce images of the internal organs of the body. This technology may be used for several purposes, including: evaluation of a developing fetus; evaluation of the heart and blood vessels of the body; evaluation of the liver, gallbladder, and kidneys; and evaluation of other soft tissue parts.

During this procedure, sound waves are transmitted through the body by a device called a transducer. The technologist will apply a gel to the body surface that enhances the transmission of the sound waves. The echoes produced when the sound waves strike an internal structure are detected by the transducer and sent to a computer. Because no radiation is utilized in these procedures, there is no radiation risk to the patient or to a developing fetus.
