Nothing to eat or drink after midnight the night before the scan and no breakfast the morning of the scan.
After your arrival at MD Imaging, you will be injected with a small amount of radioactive material that will combine with the bile in the liver to show if the gallbladder is functioning properly.
There are no side effects to the injection. The scan usually lasts for about one hour. If the gallbladder does not visualize, the scan may require additional time.
If your doctor orders CCK with the HIDA scan for gallbladder ejection fraction, the scan will take an extra half hour. CCK will be injected only when the gallbladder and bowel are seen during the scan.
Possible side effects from CCK are nausea and stomach cramps which will last only for about 3 minutes.
