During the exam – what to expect

- You will lie comfortably on a scan table while an IV is placed in your arm or hand. You will then be injected with a radioactive tracer which will go to your liver, gallbladder and small bowel. You will not feel any different after this is given to your. This usually takes about an hour.
- After your gallbladder and liver are visualized, you will be given a second medicine and images will be taken for 20 minutes. This medicine will cause your gallbladder to contract and allows us to evaluate its function. During this time you can have minor side effects to the medicine that quickly go away. The technologist will review these with you before your injection.
After the exam – what to expect
