Ultrasound

What is ultrasound?

Ultrasound uses computers and high-frequency sound waves, not radiation, to make pictures of the inside of the body. The test is painless, and there are no known side effects.

Ultrasound tests can show the structure and movement of the internal organs and blood flowing through vessels. Abdominal ultrasounds are common and may be used to if a child has abnormal or frequent vomiting, a painful or swollen abdomen, or traumatic abdominal injuries.

How do I prepare my child for an ultrasound?

There may be special rules about preparing for the test your child will have. Be sure to write down and follow any directions you are given when you set up the appointment. If you forget, call us at 832-TC4-XRAY (832-824-9729).

What happens during an ultrasound?

For most tests, your child will not have to change into a gown. You will be able to stay with your child during the entire procedure, even if you are pregnant.

For the test, your child will lie on his back on a bed in a dimly lit room. The technologist, who sits next to the bed, applies lotion to your child’s abdomen then moves a transducer, a camera that looks like a microphone, across the area. An image will be displayed on a TV screen next to the bed. Your child may be asked to lie on his side or stomach for some images.

Your child should lie very still. Be sure he does not try to touch or play with the transducer. The entire procedure, including preparation, will probably last about 1-1/2 hours.

How do I find out results of the ultrasound?

The technologist cannot tell you the results of the test. A pediatric radiologist will analyze the images and provide a report of the findings to your child’s doctor. Your child’s doctor will then notify you of the results.
