1. The purpose of the scan to evaluate the contractile function of the stomach

Often used to diagnose gastroparesis, a condition in which the muscles in the stomach wall don't work properly, slowing the push of food into the small intestine. This condition is very common in people with type 2 diabetes.

2. How is the technique performed?

The technique is performed at the Nuclear Medicine unit with well-trained medical staff.
Before the scan, you will eat some solid food (eg an omelette), some liquid mixed with a very small amount of odorless radioactive material. The radioactive material allows the camera to track the food's movement.
You will lie on the table while the camera records at 1h, 2h, 3h and 4h after eating. Each recording time is only about 1 minute. You will likely be filmed standing. You need to keep your body still during the recording.

3. How to prepare before the scan?

Except for the meal prepared by the medical staff before the scan, you should not eat or drink for 4-6 hours before the scan. If you have diabetes, bring medication or insulin.
Tell your healthcare provider what drugs you are taking, there are some drugs that can interfere with this technique:
Prokinetic agents increase gastrointestinal motility Antispasmodic drugs decrease gastrointestinal motility Ingestion Drugs with opiate ingredients such as codeine, Norco, Percocet and OxyContin
