In this pictorial essay, we review the 3-dimensional sonographic appearance of the normal gallbladder and biliary tree, as well as the appearance of congenital and acquired biliary tract disorders. Using examples, we demonstrate the advantage of 3-dimensional scanning compared with 2-dimensional sonography and, even in certain cases, magnetic resonance cholangiopancreatography.
Keywords: 3-dimensional sonography; biliary tract; gallbladder; gastrointestinal ultrasound.
