What is a Biliary Scan?

A biliary scan, also known as a HIDA, is a diagnostic exam used to evaluate the biliary tract and the gall bladder function.  A small Isotope of 99mTc-Choletec will be injected.  If an EF is needed, another injection of a non-radioactive medicine called CCK will be necessary.
