Gall bladder Radionuclide scan
Alternative names:
biliary scan; cholescintigraphy; gallbladder scan; radionuclide - gallbladder
How the test is performed:
First, the tracer (a radioactive chemical that will collect primarily in the liver and then is excreted with bile into the gallbladder) is injected into a vein (usually at the bend in the arm). The scan is then performed.
You lie face up on a table under the scanning camera (gamma scintillation camera). The scanner will detect the gamma rays being emitted from the tracer. The image of where the tracer is found in the organs is transmitted to a computer. The computer displays the image on the monitor and saves the information for future reference. A technician will operate the computer and scanner and will monitor the findings.
The test will take about 1 to 2 hours. Images take about 1 minute to acquire and are taken every 5 to 10 minutes for the first half hour and every 15 minutes during the next 90 minutes if needed.
How to prepare for the test:
Food and fluids are restricted 4 hours (or longer) before the test. You must sign an informed consent form.
Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:
How the test will feel:
When the tracer is injected into the vein, there will be a sharp prick from the needle. After the injection, the puncture site may be sore. There is no pain during the scan. Some patients experience discomfort because this test is usually performed to help determine the cause of abdominal pain.
Why the test is performed:
This test is very good for detecting acute infection (cholecystitis) or blockage of a bile duct. It is also helpful in determining whether there is rejection of a transplanted liver.
