Determination of Diameter and Angulation of the Normal Common Bile Duct using Multidetector Computed Tomography

Abstract Background/Aims: Common bile duct stones are associated with the extent of dilation of the common bile duct as well as its angulation. Multidetector computed tomography (MD CT) has a good resolution for the definition of the anatomical features of the common bile duct. Methods: The multiplanar reformation images of 398 patients that underwent multidetector CT for the diagnosis of disorders not related to the bile duct were examined. The diameter and angulation were categorized by gender and age. Results:
