【摘要】 目的建立中国人体经颈静脉肝内门体静脉分流术三维数字化可视模型,为经颈静脉肝内门体静脉分流介入手术的影像学诊断及手术方案选择提供形态学依据。方法采用我所获取的数字化可视人体数据集连续图像,运用体绘制和面绘制重建法对颈静脉、腔静脉、心脏、肝脏及肝内静脉管道系统的结构进行计算机三维重建和立体显示。结果数字化可视模型能够清晰显示经颈静脉肝内门体静脉分流术所经器官的形态结构特点、位置毗邻关系,以及肝内管道系统主支的走行分布和相互间空间解剖结构关系,并对三维重建模型进行任意经线和角度的三维测量。结论经颈静脉肝内门体静脉分流术三维重建数字化可视模型能准确反映出该路径复杂的解剖学结构特点及其空间毗邻关系,为经颈静脉肝内门体静脉分流术的影像诊断和介入治疗提供形态学依据。更多还原

【Abstract】 Objective Establishing a digitized model of the transjugular intrahepatic portasystemic stent shunt of the Chinese visible human to provide morphological data for image diagnosis and intervention planning.Methods Cross-sectional images from the Chinese visible human dataset and the dataset were reviewed and the structures were confirmed on a sectionby-section basis.Three-dimensional computer reconstructions of transjugular intrahepatic portasystemic stent shunt organs and intrahepatic vessels were generated from these data by volume rendering and surface rendering and were displayed jointly.Results The quality of the computerized 3D-reconstructed images was distinct and perfect.The internal jugular vein,vena cava,heart,liver and intrahepatic vessels and adjacent structures were all reconstructed.All reconstructed structures can be represented individually or jointly;any diameter and angle of the structures reconstructed could be measured conveniently.Conclusion The Chinese visible human dataset and the visible liver dataset can provide complete and accurate data.The digitized model of the transjugular intrahepatic portasystemic stent shunt and intrahepatic vessels offer unique insights into the complex hepatic anatomy,providing morphological data for image diagnosis and intervention planning.更多还原
