Ultrasound Exams
Ultrasound is like radar that uses sound waves to look inside the
body. It does not hurt and warm gel is used on the skin to help the
transducer move more smoothly and make better contact.
Is there any special preparation for an ultrasound?
Most ultrasound studies do not need any preparation. There are a few
exceptions:
- If it is an ultrasound of the abdomen, the child cannot eat for
approximately 4 hours before
the study.
- If it is an ultrasound of the bladder or other pelvic structures,
the child must drink a lot of fluid and not urinate before the test.
 When the test is scheduled, you will be told for how long the child
cannot eat before the study or will be told how much to drink beforehand.
The amount will depend on the child's age.
Can my child eat after the ultrasound?
Certainly!
