What is a Liquid/Solid: Gastric Emptying exam?

A Liquid/Solid: Gastric Emptying exam is a test that measures the rate of digestion of solid food by the stomach.

This exam requires the use of a radiopharmaceutical mixed in food that will be eaten by your child.

What should you do prior to the exam?

Your child cannot have anything to eat or drink for four hours prior to the exam.

Your child should not receive barium (radiographic contrast agent) 48 hours prior to the exam.

Eggs are typically used for this exam. If your child has an allergy to eggs, please contact the Nuclear Medicine Department ahead of time at 215-590-2592.

Dress your child comfortably, in clothes that are easily removed. Your child may be given a gown to change into for the exam.

We have a large variety of video entertainment to choose from, however, your child can also bring along his/her favorite video or DVD to watch during the exam.

You may want to bring a snack or drink for your child to have after the exam.

Note: Parents will be allowed to accompany the child into the exam room. It may be helpful to make other arrangements for siblings.

What should you do when you arrive?

If your appointment is scheduled at the Main Hospital:

You must check in to Outpatient Registration, on the third floor of the Main Hospital, 45 minutes prior to your scheduled appointment. This is where your registration process occurs. 

The law requires that you bring a prescription from your doctor's office stating the exam to be done and the reason for it.

If your insurance requires a referral, it must be presented at the time of registration. Proof of insurance will also need to be provided at this time.

Once the registration process is completed, the Nuclear Medicine Department will be notified. A technologist will come out to the central registration area and bring you and your child to the Nuclear Medicine exam room.

If your appointment is scheduled at the Pediatric Imaging Center at King of Prussia:

You must check in at the main registration desk, located in the main waiting room, 45 minutes prior to your scheduled appointment. This is where your registration process occurs.

The law requires that you bring a prescription from your doctor's office stating the exam to be done and the reason for it.

If your insurance requires a referral, it must be presented at the time of registration. Proof of insurance will also need to be provided at this time.

Once the registration process is completed, you will be directed to the Radiology waiting room. The Nuclear Medicine technologist will come out to the Radiology waiting room and bring you and your child to the Nuclear Medicine exam room.

What should you expect during the exam?

The technologist will ask why the Liquid/Solid exam is being done, and explain the study to you and your child. We will cook your child 2 scrambled eggs mixed with a small amount of radioactive material. There are no side effects and the medicine will not change the taste of the eggs. We serve the eggs with 2 slices of bread and 8 ounces of juice or water. Your child will need to eat the meal in ten minutes.

 After eating, your child will lie on our table and the scan will begin. We will take one picture every 10 minutes for 2 hours. Each picture takes about 1 minute. The camera will be above the table and will come close to, but will not touch your child. Your child will need to lie still for each picture but can sit up or stand between them.

We do not sedate for this procedure.

Child Life Specialists are available to answer questions you might have about how to prepare and support your child during the procedure. A child life specialist can also be present at the time of your child's appointment to explain the procedure in developmentally appropriate ways using well established preparation materials. The specialist can also be available to help implement distraction techniques to help your child better cope with the stress of the hospital experience. Please call 215-590-2001 or click the link above for more information. If your child's procedure is scheduled for the Pediatric Imaging Center at King of Prussia, you can call the Child Life Specialist directly at 215-590-3069.

What should you do after the exam?

There are no special instructions for your child to follow upon completion of this procedure.
