Volume rendering, a postprocessing computer algorithm that creates three-dimensional (3D) displays from computed tomography (CT) datasets, can create 3D cholangiographic images (volume-rendered cholangiopancreatography, or VRCP) from intravenous contrast-enhanced abdominal CT datasets without the use of a biliary contrast agent. This article illustrates the utility of VRCP in the setting of biliary obstruction due to pancreatic cancer. The 3D renderings of the intra- and extrahepatic biliary tree provide valuable information for planning biliary drainage, including the location and length of the obstruction as well as the relationship of intrahepatic ducts to liver metastases.
容积再现是一种后处理计算机算法，可从计算机断层扫描（CT）数据集中创建三维（3D）显示，无需使用胆道造影剂，就能从静脉注射对比剂增强的腹部CT数据集中创建3D胆管造影图像（容积再现胆管胰管造影，或VRCP）。本文阐述了VRCP在胰腺癌所致胆道梗阻情况下的应用。肝内和肝外胆管树的3D再现为胆道引流规划提供了有价值的信息，包括梗阻的位置和长度以及肝内胆管与肝转移灶的关系。
