The examination involves a small injection into a vein in your arm. The injection is a radioactive tracer which is taken up by your liver. The tracer is then processed by the liver, before collecting in your gallbladder in the same way as bile.
Images of your gallbladder are taken for an hour immediately after the injection. You will be positioned lying on your back on the scanning bed with the special gamma camera just above your abdomen.
If your gallbladder is not seen after one hour, you may be given a small injection of morphine. The morphine will help your bile ducts contract and thus allow the tracer to go into the gallbladder. If you have this injection there will be a 15 minute wait followed by a further three minutes of imaging.
If your gallbladder is seen after the first hour and the doctor needs to investigate how well it is contracting, then further imaging is required. You will be given a glass of full cream milk. This will encourage your gallbladder to contract. As your body needs time to process the milk, there will be a wait of one hour before a further three minutes of imaging is performed.
Our Nuclear Medicine Physician will review the images and issue a report. Once completed, the report will be sent electronically to your referring health professional.
Evaluate the function of your gallbladder.
