Gastric Emptying Scan

What is the purpose of a gastric emptying scan?
A gastric emptying scan allows physicians to determine how long it takes for food to empty from the stomach.

What will happen during the gastric emptying scan?
In preparation for the scan, you will be asked to eat two eggs containing a small amount of radioactive material. Juice, coffee and toast will be included with the meal. It is important that you eat as much of the eggs as possible. Individuals who are allergic to eggs can eat oatmeal instead.

After eating, and before the scan begins, you will be asked to use the restroom. You will then lie down on a special table. A camera that can detect radioactivity will be positioned above your stomach to take photos. It is very important that you do not move during the scan. The scan will take about two hours to complete.

How do I prepare for the scan?
You must not eat anything for four to six hours before the scan.

How soon will my doctor get the results?
After the procedure is complete, a nuclear medicine physician will study the pictures along with your medical history to make an assessment of what the images show. He will then dictate a report that will be forwarded to your physician within five to seven business days. If your doctor needs the results sooner, he/she may contact the nuclear medicine physician on the day of the exam.

How do I make an appointment?
Your doctor will write an order or prescription for the test. The doctor will either give you the order or have it faxed to the hospital. You may then schedule your appointment by calling the Nuclear Medicine Department at 847-723-5050.

If I still have questions, who should I call?
