It is formed by the union of the common hepatic duct and the cystic duct (from the gall bladder). It is later joined by the pancreatic duct to form the ampulla of Vater.

Multimodality Imaging of Pancreatic and Biliary Congenital between the CBD and the pancreatic head: The CBD is partially covered posteriorly by pancreatic tissue in 51.5% of the population, totally covered in 30%, and not covered at all in 16.5% (Fig 4). Occasionally, the CBD courses lateral to the pan-creatic head (5). Figure 3. Normal pancreatic ductal anatomy. Primär sklerosierende Cholangitis - Wissen für Mediziner Die primär sklerosierende Cholangitis (PSC) ist eine chronisch fortschreitende Entzündung der intra- und extrahepatischen Gallenwege, die im Verlauf über eine … The Cystic Duct: Normal Anatomy and Disease Processes In most cases, the normal cystic duct is not seen at US. However, with optimal technique, the normal cystic duct can be visualized in up to 50% of cases as an anechoic tubular structure connecting the gallbladder and bile duct (,,, Fig 3).

However, in early stages the biliary system may appear normal at imaging. Biliary Imaging: Multimodality Approach to Imaging of Biliary In patients with normal liver function, the hepatobiliary phase is imaged approximately 20 minutes after contrast material administration with three-dimensional fat-saturated gradient-echo T1-weighted imaging.
