Colonic Transit Scan
A Colonic Transit Scan evaluates bowel transit disorders.
What will happen when you have your Colonic Transit Scan
A colonic transit scan is conducted over 5 consecutive days:
Day 1: When you arrive in the nuclear medicine department you will be required to drink a cup of milk mixed in with a small amount of a radioactive tracer. If you are unable to drink milk you can have water instead. You will then be required to return to the nuclear medicine department 6 hours later for 20 minutes of images. You can eat and drink as normal after you have had the radioactive drink.
Day 2 - 5: You will be asked to return to the nuclear medicine department at the beginning of each day at approximately 8:00am for 20 minutes of imaging.
