A HIDA Scan evaluates the function of the gallbladder and bile ducts.
What to Expect
- A HIDA Scan requires a small injection of radioactive tracer through a vein.
- The tracer accumulates in the liver where it is excreted into the bile ducts, bringing the bladder into view.
- Once the gallbladder is visualized, another injection is given, which is a normal enzyme the body produces called CCK; it contracts the gallbladder and tells how well it is functioning.
- This test takes between 1-1/2 hours and 4 hours. It will be closer to 4 hours if the gallbladder does not visualize.
- The patient should have nothing to eat or drink 5 hours before the scan and should not have a barium study in the past 5 days.
- The patient should not have Morphine or Demerol 6-8 hours prior to the scan.
