Abstract:
The biliary tree is a three-dimensional system of channels that bile flows from the hepatocytes to the gallbladder and to the intestine. Size of the common bile duct (CBD) is a predictor of biliary obstruction and, therefore, its measurement is an important component of
biliary system evaluation. Factors like age, height, weight, BMI, previous cholecystectomy,
drugs, and type of imaging modality affect CBD diameter, but the duct significantly dilated
due to obstructive biliary pathology
