Hepatobiliary Scan, popularly known as HIDA Scan, is a medical imaging procedure that helps doctors evaluate the function and structure of the liver, gallbladder, bile ducts, and small intestine. This test is essential for identifying abnormalities such as blockages, infections, or diseases within the hepatobiliary system, which includes the liver, gallbladder, and bile ducts.The liver produces a digestive fluid called bile, which aids in the digestion of fats in the small intestine. The gallbladder stores this bile and releases it when necessary. The bile ducts are tubes that carry bile from the liver to the gallbladder and the small intestine. The proper function of these organs and ducts is critical for the digestion and absorption of nutrients.

HIDA Scan uses a small amount of radioactive tracer material that is injected into the bloodstream. This tracer travels to the liver, where it is taken up and then excreted into the bile. A special camera is used to capture images as the tracer moves through the hepatobiliary system.
Fasting: You may be asked to fast for 4 to 6 hours before the test. It is essential as eating might cause the gallbladder to contract, which can affect the results.
Medications: Inform your doctor about any medications you are taking. You may be advised to avoid certain medications before the scan.
Allergies: Tell your doctor if you have any allergies or have had a reaction to any contrast material in the past.
Clothing: Wear comfortable clothing. You may be asked to wear a gown during the test.
Pregnancy and Breastfeeding: If you are pregnant or breastfeeding, inform your doctor, as this test might not be suitable.
You will be asked to lie on an examination table.
A healthcare professional will inject a small amount of radioactive tracer into a vein in your arm.
You will have to wait for the tracer to travel through your hepatobiliary system.
The camera will take images over a certain period. This can take anywhere from 1 to 2 hours.
You must remain still during the imaging process.
It helps in diagnosing diseases or abnormalities within the liver, gallbladder, bile ducts, and small intestine.
It can detect blockages in the bile ducts.
It can help evaluate gallbladder function.
It can be used to detect bile leakage or infection.
The HIDA Scan provides functional information about how bile is being processed in your liver and how it flows through your bile ducts and gallbladder. This helps to identify if there are any blockages or dysfunction within this system.
