An ultrasound scan is a procedure that uses high frequency sound waves to create a picture of a part of the inside of your body.
The ultrasound scanner has a microphone that gives off sound waves. The sound waves bounce off the organs inside your body, and the microphone picks them up. The microphone links to a computer that turns the sound waves into a picture on the screen.


Your doctor may order an ultrasound if you’re having pain, swelling, or other symptoms that require an internal view of your organs. An ultrasound can provide a view of the:

• bladder,
• brain,
• eyes,
• gallbladder,
• kidneys,
• liver,
• ovaries,
• pancreas,
• spleen,
• thyroid,
• testicles,
• uterus,
• blood vessels.
