One of our sonographers will escort you into one of our scan rooms. The rooms are kept fairly dark so that we can see the screen (just like a movie theater).
Your child will be placed on a soft table for at least 30 minutes or longer. The sonographer will then place warm lotion onto your child’s body and take pictures for the doctor. The lotion is clear and easily removable. The sonographer will slide the transducer that acts like a camera across the part of the body being examined.
Sometimes during ultrasound, the doctor even comes in and scans too. The ultrasound test does not hurt, and ultrasound waves will not harm your child. Parents are encouraged to stay with your child during the test.
Have your child wear loose clothing. During the ultrasound test, your child will need to lie fairly still on the table, so it is a good idea to bring a favorite movie to watch. If you forget, we have a selection of movies.
Before the Test
Before coming to the hospital read the explanation and explain to your child what will happen during the ultrasound test.
If you child is an infant and drinks from a bottle, it is a good idea to bring along a bottle for a baby to drink during the test. Also bring a pacifier or special toy to help calm your child.
For older children, bring books or electronic games to occupy them while waiting.
