螺旋CT三维重建对胆囊三角解剖结构研究

目的评价螺旋CT三维重建对胆囊三角解剖结构的识别能力。方法选择30例肝胆系螺旋CT增强检查资料,将所获得的图像数据进行MPR、SSD、MIP等后处理重建,评价重建图像对胆囊三角区解剖关系的显示能力。结果30例病例通过MIP重建,显示胆囊动脉和肝右动脉血管形态清晰、走行自然,动脉分支小血管也得到满意显示;通过SSD三维重建,全部病例显示血管空间结构光滑、逼真,但13例动脉分支未能显示;通过不同斜面MPR重建,全部病例胆囊三角解剖结构都能清晰显示。结论螺旋CT三维重建效果良好,能够充分识别胆囊三角区结构关系,为临床外科提供解剖形态学依据。

Study of Three Dimensional Reconstruction of Calot Anatomy

Objective To evaluate the value of three dimensional reconstruction in calot anatomy. Methods 30 cases spiral CT enhancing scaning of liver and gallbladder system.By reconstruction of MPR,SSD and MIP, evaluate showing capability in calot. Results MIP can Show cystic artery and the right hepatic artery clearly.And sub-branches of artery can also been shown.SSD can show the spatial relafionalship of blood vessels smoothly and clearly.But 13 cases of SSD can not show sub-branches of artery. All cases of MPR can show the spatial relationalship of calot clearly. Conclusion 3D reconstruction can identify anatomy of Calot,and provide anatomy gist for clinic surgery.
