Final answer:
A HIDA scan is a medical imaging procedure used to evaluate the function of the gallbladder and bile ducts. It involves injecting a radioactive tracer and using a special camera to visualize these structures. It can help diagnose problems like gallstones or inflammation.
Step-by-step explanation:
A HIDA scan, also known as a hepatobiliary scan, is a nuclear medicine imaging procedure used to evaluate the function of the gallbladder and bile ducts. It involves injecting a radioactive tracer into the patient's vein, which is then taken up by the liver and excreted into the bile. The tracer helps to visualize the gallbladder, bile ducts, and liver on a special camera.
The scan can provide valuable information about the presence of gallstones, inflammation or infection of the gallbladder, or any abnormalities in the bile flow.
For example, if a patient is experiencing abdominal pain and the doctor suspects a problem with the gallbladder, a HIDA scan can be performed to determine if the gallbladder is functioning properly or if there is an obstruction in the bile ducts.
