What does it mean if you have no bile duct dilation?

If you have no bile duct dilation, it means that your bile ducts are not dilated or enlarged. Bile ducts are small tubes that carry bile from the liver to the gallbladder and small intestine. Dilation of the bile ducts can be a sign of several underlying medical conditions, such as gallstones, tumors, inflammation, or scarring. Therefore, having no bile duct dilation is generally considered a normal finding and indicates that your biliary system is functioning properly.
