Your physician has requested that you have a hepatobiliary scan. This is a safe, simple, non-invasive way to evaluate for liver and gallbladder disease. The study requires you to be fasting at least 4 hours before the examination. The test also requires a sonogram of the gallbladder within 6 months prior to the exam. No pain medication may be taken for four hours before the examination. There are no dietary restrictions after the examination. The test also requires you to receive an injection in an arm vein. This injection consists of a very small amount of radioactive material. The radioactivity associated with the scan is negligible and there are no ill effects from it. To evaluate the emptying ability of the gallbladder, you will also receive a medication called cholecystokinin (CCK) to stimulate the gallbladder's contraction (Gallbladder Ejection Fraction).
To outline our requirements, you will:
- After registration report to Medical Imaging and check in.
- You will then be escorted to Nuclear Medicine.
- A short history will be taken
- You will be escorted to the examining room.
- You will be positioned on your back on a scanning table.
- Receive the injection into an arm vein.
- Lie quietly for 1 hour while pictures are taken of your abdomen.
- After the first hour of imaging is completed and if the gallbladder is visualized, you will receive an intravenous injection of CCK. Images of your abdomen will be taken for another 45 minutes. These images will determine your gallbladder ejection fraction.
- In the event that your gallbladder does not visualize in the first hour you may be given a small amount of morphine. The morphine may or may not stimulate the visualization of your gallbladder. If morphine is administered we ask that you arrange for transportation home.
- Additional delay pictures may be required at the discretion of the reviewing physician.
- Once the test is complete a Radiologist will read the test and results will be sent to the ordering physician.
Note: Inpatients will be transported to Nuclear Medicine for this test.
