Due to constant innovations in radiological and surgical techniques, more accurate results are expected in the diagnostic and therapeutic procedures related to hepatic pathology. The aim of this work was to demonstrate the normal hepatic vascular and biliary anatomy using cadaveric livers and CT scans of the affected livers. Furthermore, using the CT scans, the authors intended to illustrate the most common morphological variations of the vascular and biliary anatomy. Four human cadaveric livers were injected with colored silicone mixed with radiological contrast solution in the common bile duct, in the proper hepatic artery, in the portal vein and in the inferior vena cava near the ostia of the hepatic veins (only one of these structures was injected in each liver). After obtaining the CT scans, 3D rendered models were created, which demonstrated the normal hepatic anatomy of the vascular and biliary structures. The International Anatomical Nomenclature was used for their classification (based on Couinaud's work). The 3D rendered CT models were also modified to illustrate the most common normal variations of the hepatic anatomy (found in the literature).
由于放射学和外科技术的不断创新，预计在与肝脏病理学相关的诊断和治疗程序中会取得更准确的结果。这项工作的目的是使用尸体肝脏和患肝的CT扫描来展示正常的肝脏血管和胆道解剖结构。此外，作者打算利用CT扫描来说明血管和胆道解剖结构最常见的形态变异。对四具人类尸体肝脏进行了注射，将彩色硅胶与放射学造影剂溶液分别注入胆总管、肝固有动脉、门静脉以及肝静脉开口附近的下腔静脉（每具肝脏仅注入其中一个结构）。获取CT扫描后，创建了三维渲染模型，展示了血管和胆道结构的正常肝脏解剖。使用国际解剖学命名法对其进行分类（基于库尼亚德的研究）。还对三维渲染的CT模型进行了修改，以说明肝脏解剖最常见的正常变异（文献中发现的）。
