摘要: 目的:构建顶枕沟在基于连合间径定位体系中的立体定位数据集及其内表面平面回归方程。方法:30名正常成人颅脑横断层MRI数据经格式转化导入Photoshop CS软件包, 经过图像的严格配准, 以顶枕沟的最内侧点为起始点, 向外取X绝对值为3 mm倍数点为取样点, 测量、记录该点坐标的X、Y值, X、Y值从Photoshop信息面板栏上显示、读取, Z值等于所在层面与双连合层面间相间隔的层面数和层间距的乘积, 所有取样点坐标值组成顶枕沟在三维坐标系中的立体定位数据集。取样点坐标数据集导入SPSS 16. 0软件, 求解其空间拟合平面方程。结果:构建了顶枕沟内表面在三维坐标系中的立体定位数据集, 在矢状面上Z对Y的直线回归方程为:Z=-0. 774Y-26. 975(右侧), Z=-0. 760Y-28. 599(左侧)。结论:在三维空间内构建的顶枕沟立体定位数据集及其内表面直线回归方程, 能为基于立体定向技术的神经外科、介入放射治疗等提供三维立体定位解剖学基础。Abstract: Objective: To build a stereotactic data set and internal surface regression equation of cerebral parietooccipital sulcus. Methods: The cross-sectional MRI data of 30 normal adult were imported into Photoshop by form transition. Through the strict registration of the image, the coordinate system of the software coincide with the system based on AC-PC line were made. The X and Y values of sample points with per 3 mm of the X-axis which began from the most inside point of the parietooccipital sulcus and along the parietooccipital sulcus line were measured and recorded and the multiplication of the thickness and number of the layer acted as Z values. All data of sample points of the parietooccipital sulcus were collected and analyzed by SPSS 16. 0 software, and plane equation was solved. Results: The three-dimensional stereotactic data set and internal surface regression equation of the pareitooccipital sulcus were constructed. In sagittal plane, the straight line regression equations of Z toward Y were 0. 774(Z) and 26. 975(Y) in right side and 0. 760(Z) and 28. 599(Y) in left side. Conclusions: The stereotactic data set and internal surfacicial regression equation of the pareitooccipital sulcus are constructed in the three-dimensional coordinates, which can play an important role in the construction of stereotactic surgery, and provide anatomical basis for interventional radiologic treatment.
