Comprehensive Biliary Tract Visualization

The imaging data obtained from the scans were studied on a workstation with 3D and 2D competence and multiple editing options. The reconstruction of the image and postprocessing of the source images of MRCP were achieved using an image of maximum intensity projection (MIP) formed in the coronal plane that showed the entire anatomy of the biliary system. Three-dimensional models of the hepatic ducts and common bile ducts were produced via a technique known as volume rendering (VR). The MIP and VR images were projected and magnified at a suitable angle to view the minor capacity of the standard common bile duct and intrahepatic bile ducts. A distinct consideration was given to the intrahepatic biliary radicles, especially the insertion of the right posterior sectoral duct, since it is considered the most crucial abnormality for optimal visualization. After the MIP and 3D VR images were obtained, the source images of the thin coronal sections and native axial sections were reviewed, which allowed for the optimum assessment of small accessory bile ducts or any of the small accessory bile duct branches.
