How is a hepatobiliary scan performed?
An IV is placed in the vein of your arm. A small amount of a radioactive material is injected through the IV site. you will be asked ot lie down on a table. A camera that can detect radioactivity will be positioned above your stomach to take photos. It is very important that you do not move during the scan. If, after one hour, your gallbladder can be seen with the scanning equipment, you will be given a special medication called CCK that will provide informaiton about how well your gallbladder is working. If your gallbladder cannot be seen, you may be given a small dose of medication, which will aid in visualizing the gallbladder. The scan will take about 30 minutes to complete. If you receive morphine during your scan, you must have someone drive you home.
