The biliary system consists of the organs and ducts bile ducts gallbladder and associated structures that are involved in the production and transportation of bile.

Biliary tract anatomy. It carries bile from the liver and gallbladder to the small intestine. The transportation of bile follows this sequence. The biliary tract biliary tree or biliary system refers to the liver gall bladder and bile ducts and how they work together to make store and secrete bile.

Anatomy of the biliary system. Posteriorly transverse colon and the proximal duodenum. The radiographic evaluation of the intrahepatic biliary system mainly consists of computed tomography ultrasonography and magnetic resonance cholangiography with hepatobiliary contrast and hepatobiliary scintigraphy.

Bile canaliculi hepatic cystic and common bile ducts. Intrahepatic biliary system anatomy and radiology. Duct of the biliary tract that is formed when the common hepatic duct and the cystic duct combine.

When the liver cells secrete bile it is collected by a system of ducts that flow from the liver through the right and left hepatic ducts. The biliary system consists of the organs and ducts that help to make and transport bile. Intrahepatic bile duct anatomy figure 1 the anterior hepatic duct lies vertical located to the left of the anterior branch of the portal vein.

Inferiorly biliary tree and remaining parts of the duodenum. The biliary system is the part of the accessory digestive tract that is responsible for producing storing and transporting bile. There is significant variation in the biliary tree with the classical description below thought to be present in 60 of the population 2.

The direction of the posterior duct is more horizontal running superior being epiportal in the hjortsjö crook 2 to the anterior portal branch and joins the anterior duct. Bile canaliculi unite to form segmental bile ducts which drain each liver segment.

The transportation of bile follows this sequence. The main goal of each imaging modality in each disease process is different. Just below the porta hepatis these 1 to.
