Hepatobiliary Scan (HIDA)
What is a HIDA scan?
A HIDA scan may be performed to assess gallbladder function and obstruction, or to look for bile leaks.
What should I do to prepare for my exam?
Do not eat for four hours before the HIDA scan. Water is okay. Eat a “fatty” meal the night before (e.g., drink a glass of whole milk). This will have the gallbladder ready for the study.
What will happen during a HIDA scan and how can I get my results?
The patient lies on a table with the gamma camera over the abdomen. The patient will be injected intravenously with a small amount of radioactive tracer. This material goes from the blood stream to the liver, and then to the gallbladder. Images start immediately. A second injection may be given 45 to 60 minutes into the study. This injection will help to evaluate gall bladder function. The study takes 90 minutes.
The physician who interprets the scan will send a report to your physician, who will then share the results with you.
