What is a Nuclear medicine gastric emptying study?

This examination is used to investigate the function of your stomach. It will assess how fast/slow food passes through your stomach. Although time consuming, it is simple and non-invasive. 

You may have been referred for this procedure if you have or are suspected to have: 

  • Gastroparesis - a disease where the stomach muscles are weakened, resulting in insufficient grinding and poor emptying of food from the stomach. 
  • Dumping Syndrome - also known as rapid gastric emptying, food moves too quickly from the stomach to small bowel.
  •  Or unexplained nausea and vomiting.

How do I prepare for the procedure? keyboard_arrow_down

Preparation may vary from clinic to clinic and you will be advised on the specifics at the time of booking.  However, as a general guide you may be asked to:

  • Stop certain medications that effect gastric movement (please discuss this when booking your scan).
  • Fast for six hours before your scan (four hours if diabetic). 
  • Remove any metal objects eg. belts and jewellery - underwear and zips are ok.
  • If you are breast feeding there is no need to interrupt the feeds. 
  • If you are pregnant please discuss this with the Nuclear Medicine Physician before proceeding.

What happens during the procedure? keyboard_arrow_down

  • On arrival you will be asked to eat a small meal, consisting of one egg (scrambled) on a piece of toast. You will be asked to eat this within 5 minutes. A small amount of radioactive agent is added to the egg which allows us to track the movement of food through the stomach (there are no side effects from this radioactivity).
  •  Once you have finished the meal imaging will commence immediately. • A Nuclear Medicine technician we take you into the room and will assist you to lie down on the gamma camera bed and the camera will move in very close over your abdomen - it will not touch you and there are no sounds from the machine. 
  • You will then be imaged every hour for four hours - please feel free to bring a book or activity to use between the images.
  • Although you are allowed to leave the department, you cannot eat or drink until the study is over. Most people choose to stay in the waiting room.

* If you have any allergies please let staff know when booking your scan and an alternative meal can be arranged.
