Gastric Emptying Study

A gastric emptying study will evaluate the length of time it takes food (both solid and liquid) to pass through the stomach into the small bowel.

How do I prepare for the exam?

Do not eat or drink anything after midnight the night before the exam.

What can I expect during the exam?

This exam is conducted by a specially registered technologist in molecular imaging.

You will eat a light breakfast consisting of an egg sandwich and orange juice that has been prepared with a radioactive tracer.

Once you are finished with your meal, the technologist will have you lie on the scan table, and scans will be done every 15 minutes for two hours, as the food is digested and passed through the stomach.

The exam will take approximately 2 to 2.5 hours.

What can I expect after the exam?

Unless your physician tells you otherwise, you may resume your normal activities after your molecular imaging scan. If any special instructions are necessary, you will be informed by a technologist, nurse or physician before you leave the molecular imaging department.

Your scan will be read by a radiologist specially trained in molecular imaging. A written report will be sent to your physician, who will contact you with results.
