The patient is to fast (not eat or drink anything) for 6 - 8 hours prior to your exam. You should expect to be at WDH for approximately 2 hours for this procedure. Please let your doctor who is scheduling the exam for you know if you are allergic to eggs, as eggs are used in this procedure.
What to Expect:
You will be escorted back to the Nuclear Medicine suite by one of our team members. In the Nuclear Medicine suite, a Technologist will explain the procedure to you, talk to you about your symptoms (if any) and medical history. You will be given a small amount of scrambled egg tagged with a radiopharmaceutical in it to eat.
You will ingest the scrambled egg, you will be offered a few sips of water to wash it down, and then the Technologist will assist you onto the imaging table. From there, the Technologist will position the camera so that it is above your abdomen and he/she will begin imaging your stomach to watch and see how well you digest the eggs.
The scan itself takes 90 minutes. For maximum comfort, you will lie on your back with a pillow under your head and knees be covered with a warm blanket. Feel free to bring along your favorite DVD movie or music CD or you can choose from our selection.
