CCK-HIDA scan is procedure used to check the function and the condition of the gallbladder and the ducts leading in and out of it. It can help determine if a person has form of gallbladder disease or if the gallbladder is functioning properly.
What to expect
A radioactive chemical (hydroxy iminodiacetic acid or HIDA) is injected intravenously (IV) into the person. The chemical is removed from the blood by the liver and secreted into the bile which is produced by the liver. The test chemical then disperses into the bile ducts, the gallbladder, and the intestine. The radioactive substance will remain in the body temporarily until it is passed through urine or stool.
A camera (nuclear scanner) that senses radioactivity is then placed over the stomach and images of the liver, bile ducts, and gallbladder are obtained over the course of about two hours.
An injection of CCK (cholecystokinin) is administered and additional images will be taken. CCK is a medication that causes the gallbladder to contract. During the injection, a person may experience abdominal cramping or pain and nausea, however this will pass quickly. The images obtained before and after the CCK are examined and interpreted by a radiologist.
