What is a HIDA scan?
A HIDA scan or hepatobiliary iminodiacetic acid (HIDA) scan is an imaging procedure to track the flow of bile from your liver to your small intestine and also to evaluate your gallbladder function.
How should I prepare for a HIDA scan?
You should fast for 4 to 6 hours prior to the scan. Also, do not take morphine or morphine-based pain medicine for 12 hours beforehand.
