尸体肝脏横断面解剖与CT增强影像对比研究对活体肝移植的术前评估

目的 用国人尸体肝脏薄层横断面结构形态学信息，为人体肝脏断层影像学的识别和活体肝移植提供解剖学依据。方法选取人体尸体肝脏连续横断面图像进行解剖形态学观察，与其相对应的CT增强图像对照研究，并完成计算机三维重建。结果在尸体肝脏连续横断面图像与其相对应的CT增强图像，清晰显示肝内管道系统主支的走行分布特点，三维重建图像能清晰显示肝内血管空间结构特征以及所支配区域的空间体积。结论通过对肝脏横断面解剖结构的探讨，CT增强图像能够完整而精确地反映出该区域复杂的解剖学结构特点，为活体肝移植的术前评估提供坚实的形态学基础。

Comparative study on the transverse sectional anatomy and image of CT contrast enhancement on cadaveric liver for living liver transplantation

Objective To provide the morphological imaging analysis of-living liver transplantation with basic anatomic information by using the thin transverse sectional anatomy of the Chinese visible human liver. Methods The sectional images collected from the Chinese visible human liver were observed meticulously and were compared with the corresponding CTE on the axial planes and were recon - strueted on personal computer with 3D photo segmental software. Results Intrahepatic vessels were clearly observed on both transverse sectional anatomic images of visible human liver and corresponding CT images. All reconstructed structures could be represented individually or jointly, and 3D reconstructed images were helpful in provideing the best morphological fundament for the living liver transplantation. Conclusion The comparative study between sectional anatomy and CT imaging of visible liver can offer unique insights into the complex hepatic anatomy, and provide accurate morphological data for imaging diagnosis and surgery guidance planning.
