HIDA biliary scan
Informed by recognized medical guidance
Overview
A HIDA scan (hepatobiliary iminodiacetic acid scan) is a type of nuclear medicine imaging test. It uses a small amount of radioactive tracer to look at how well your gallbladder, bile ducts, and liver are working. The tracer is injected into a vein, then a special camera takes pictures as the tracer moves through your bile system.
Key facts
- A HIDA scan helps diagnose problems with bile flow, such as blockages, inflammation, or gallbladder dysfunction.
- The test is painless and typically takes 1 to 2 hours.
- You may need to avoid eating for a few hours before the scan, as food can affect bile flow.
HIDA scans are a common and safe test for people with suspected gallbladder or bile duct issues. They are performed in many hospitals worldwide.
This test is usually done for adults and children who have symptoms like abdominal pain, nausea, or jaundice (yellowing of the skin or eyes). It is also used in infants to check for biliary atresia, a condition where bile ducts are blocked.
