Nuclear Medicine Gastric Emptying Scan

The Gastric Emptying Scan studies how foods and liquids move out of your stomach and into your intestines. Gastric emptying scans can be done as a solid or liquid, depending on what your physician wants to study.

When you have a  Nuclear Medicine Gastric Emptying Scan, you cannot eat or drink from midnight the night before your exam until you have your procedure.

For a solid exam, when you arrive in Nuclear Medicine, you will be asked to eat some oatmeal with a small amount of medicine in it. You will then be asked to lie on the exam table and the scanner will remain stationary over your body. This procedure lasts about one hour.

For a liquid exam, when you arrive in Nuclear Medicine, you will be asked to drink some water with a small amount of medicine in it. You will then be asked to lie on the exam table and the scanner will remain stationary over your body, measuring how long it takes for the liquid to move out of your stomach. This procedure lasts about 30 minutes.
