This scan demonstrates not only liver function, but also the function of the gallbladder. It is commonly used to diagnose abnormal function of the gallbladder. It also examines the gallbladder and the ducts leading into and out of the gallbladder.
Many people have gallstones without ever having symptoms.
However, these stones can cause acute abdominal pain by obstructing the gallbladder and the flow of bile. This is a very simple test to determine if gallbladder is obstructed. This material is taken up by the liver and excreted into the biliary tract. In a healthy person, this material will pass through the bile ducts and into the cystic duct to enter the gallbladder. It will also pass into the common bile duct and enter the small intestine, from which it eventually passes out of the body in the stool.
