[Development status of biliary tract imaging technology].

Structure of biliary system is complex as well as various, making troubles for optimal surgical treatment of biliary disease. Remarkable imaging of biliary system helps surgeon evaluating patients and planning surgeries. There are several methods to obtain accurate anatomical information of biliary system, such as X-ray fluoroscopy, MRI and fluorescence-based imaging. Each has its own advantages and disadvantages. Combination of multi-model imaging technologies may improve visual result of anatomical information of biliary tract. More resolvable, legible, and sequential imaging technology of biliary system remains further study. This article reviews various cholangiography methods widely used in the clinical setting.
