Ultrasound

Also known as: ultrasonography, sonography.

What is an ultrasound?

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.

Is any special preparation needed?

In some cases, the patient may need to avoid eating and drinking beforehand, as well as not wear jewelry during the test. Some ultrasound tests will require the patient to avoid urinating, so it can be done with a full bladder.

What to Expect During the Procedure

Step 1: Getting Ready

• In some cases, the child may need to avoid eating and drinking beforehand, as well as not wear jewelry during the test.
• Some ultrasound tests will require the patient to avoid urinating, so it can be done with a full bladder.
• You and your child will be walked from the waiting room to the ultrasound room where you will see a computer on wheels and an exam bed.
• Your child may be asked to change into a hospital gown and lie on the “picture bed” for the ultrasound.

Step 2: Taking Pictures

• The technologist will put a jelly-like substance on the ultrasound wand part to begin to take the pictures.
• The technologist will place the wand on the body part being examined.
• As mentioned above, remind your child that the ultrasound does not hurt and the jelly is cold.  The wand might even tickle.

Step 3: Results

Your doctor will contact you in about 48 to 72 business hours.
