This is a test to look at the function of the liver and the drainage of the gall bladder. Before the test it is important that you have nothing to eat or drink for four hours. You will be given an injection in your arm of a small amount of radioactivity that settles in the liver cells then drains through the bile ducts into the gall bladder. The injection feels very similar to a blood test and has no side effects.
You will need to lie on a special couch while the gamma camera takes a series of pictures for about up to an hour, you do not have to undress for this. The camera does not go over your head, nor will you go through a tunnel. You may also be given a high fat drink to speed up the drainage process.
After all the images are completed, the technologist will check them before the patient goes home. We will not be able to give out the result of the study immediately but a written report will be sent to the referring doctor. There are no other side effects from the test.
