Colonic Transit Scan

What is the scan for?

The scan shows how quickly the motions are going through your large bowel, how constipated you are and if there is blockage at a particular site.

What preparation is required?

Stay off any bowel medications including laxatives for 3 days before the test.

What about the injection?

There is no injection.  On Monday morning, you come in and receive a small drink of radio-tracer.  You can leave straight away.  There are no side effects and you will not feel tired and can drive a car.

What about the pictures?

You return 6 hours later on the same day for a 10 minute picture of your stomach.  Then on the next 4 days (Tuesday – Friday) you come back each morning for further 10 minute pictures of your stomach.  During this time, stay off your bowel medications and have your normal diet.

When do I get the results?

Results will be available the following day after 2pm.
