A Hepatobiliary scan, also called a gallbladder or HIDA scan, is used to evaluate upper abdominal pain, determine causes of jaundice and identify obstruction in the gallbladder.
A hepatobiliary scan can take up to 2.5 hours.
During your exam, an IV line will be started in a vein in your arm, and you will receive an injection of a small amount of radioactive tracer. The tracer allows your gallbladder to be seen by the nuclear medicine camera.
The camera will capture an image every five minutes to monitor when your gallbladder becomes enlarged, which can take about an hour. Once your gallbladder enlarges, you will receive an injection of CCK (cholecystokinin) through the IV line. CCK makes the gallbladder contract, enabling the camera to capture images showing gallbladder function.
Your images will be interpreted by one of our board-certified radiologists. The findings will be sent to your healthcare provider who will then contact you to discuss the results.
Unless directed otherwise, you may drive, resume your normal diet, exercise and take all prescribed medications after your appointment.
