What is an ultrasound?

Also known as: ultrasonography, sonography.

An ultrasound is a large camera that helps doctors understand more about the tissues and organs inside the body. These painless exams help doctors see images in further detail.

A special wand covered in a jelly-like substance is often used to help the wand slide across the skin. Some children say the jelly feels cold.

Ultrasounds may take anywhere from 15 to 40 minutes, depending on how well the child cooperates.
