Imaging of Common Biliary Tract Diseases

Both CT and MR imaging can be crucial for the final diagnosis of most biliary diseases, with both modalities allowing localization diagnosis, qualitative diagnosis, and detailed evaluation of the biliary tract (Yeh et al. 2009). Three-dimensional reconstruction represented by CT and MRI plays a significant role in guiding precision surgery, providing important information for tumor infiltration characteristics, adjacent important vascular structures, variations, and quantitative evaluation. This chapter focuses on the imaging features of these two examination techniques in the diagnosis of biliary system diseases.
