This is a test to look at the drainage of lymphatic fluid from either the arms or legs. You will be given an injection of a small amount of radioactivity into either your hands or feet depending on which limb is giving you problems.
You will need to lie on a special couch while the gamma camera takes a series of pictures; there is no need to undress for this, the camera does not go over your head, nor will you go through a tunnel. Imaging may take up to an hour and a half, but you will be able to get up and walk around between images.
After all the images are completed, the technologist will check them before you go 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 side effects from the test.
