A Hida Scan is performed to evaluate biliary patency (blockages due to gallstones in the gallbladder or biliary ducts). It can also be used to evaluate gallbladder dysfunction.
- A nuclear medicine technologist will start an intravenous (IV) site in one of the patient's arms.
- If you have not eaten in over 12 hours, a medication called Sincalide, may be injected to stimulate the gallbladder.
- You will be injected with a radioactive tracer which is then followed under a gamma camera for one hour.
- If within the first hour the gallbladder is visualized and there is no evidence of blockage, the technologist will begin the second part of the exam which allows for the evaluation of gallbladder function.
- You may receive a slow infusion of a drug known as Sincalide, during which you will also be under the gamma camera for imaging.
- Total time for a Hida scan may be up to 2 hours unless delayed imaging is ordered by the radiologist.
After the procedure
- You will follow up with ordering doctor.
- Please bring a prescription if your doctor has given one to you.
- Nothing to eat or drink four hours prior to exam.
- No Morphine products or narcotic pain medications 6 hours before exam.
- If you are pregnant or suspect you may be, contact your referring doctor.
- Your exam may require additional imaging that will extend the exam time.
- Tell the technologist if you are planning to travel out of the country.
