Construction of stereotactic data set and projection regression analysis of Heschl′s gyrus

目的:构建大脑颞横回基于连合间径(AC-PC)定位体系中的立体定位数据集及其平面投影回归方程。方法:将30名健康成年人颅脑横断层磁共振数据经格式转化导入Photoshop CS软件包,经过严格的图像配准,建立以AC-PC中点为原点的三维立体坐标系,从颞横回最内侧点为起始点,向外测量、记录该点坐标的X、Z值,Y值为所在层面图像距离AC-PC平面的层数与层间距的乘积,所有取样点坐标值构成颞横回在三维坐标系中的立体定位数据集。利用Excel表格对所获得的数据作投影散点图,利用SPSS 22.0统计软件求得其在横、矢、冠状面上的空间拟合平面回归方程。结果:男性颞横回左右侧X坐标值差异无统计学意义(P>0.05),Z坐标值左右两侧差异有统计学意义(P<0.05);女性颞横回左右侧X、Z坐标值标左右两侧之间差异均无统计学意义(P>0.05)。大脑颞横回内侧缘在横断上Y值对X值的回归方程右侧:Y=29.3-6.48X+0.25X^2-0.002 5X^3(P<0.01),左侧:Y=-108-4.73X-0.05X^2(P<0.01);大脑颞横回内侧缘在矢状面上Z值对Y值的回归方程右侧:Z=-0.8-0.35Y-0.004Y^2(P<0.01),左侧:Y=0.1-0.2Y+0.008 64Y^2-0.000 569Y^3(P<0.01);大脑颞横回内侧缘在冠状面上Z值对X值的回归方程右侧:Z=54.8-2.63X+0.03X^2(P<0.01),左侧:Z=58.9+2.82X+0.03X^2(P<0.01)。结论:构建大脑颞横回立体定位数据集及直线回归方程,对颞横回及其邻近区域疾病的立体定向神经外科和介入放射等治疗方法有较大的临床应用价值,同时对于揭示大脑颞横回的形态学规律有重要的意义。

Objective:To construct the stereotatic localization data set and its plane projection regression equation of the Heschl’s gyrus based on the AC-PC localization system.Methods:The transverse tomography data of 30 healthy adults were imported into Photoshop CS software package by format transformation.After strict image registration,a three-dimensional sitting system with AC-PC midpoint as the origin was established.From the side point of Heschl’s gyrus as the starting point,the X and Z values of the coordinates of the point were measured and recorded,and the Y value was the product of the number of layers between the image layer and AC-PC plane and interlayer spacing.The stereotactic data set in a three-dimensional coordinate system of Heschl’s gyrus was constituted by the coordinate values of all sampling points.The projection scatter plot was made by Excel table,and the spatial fitting plane regression equation on the transverse,sagittal and coronal planes was obtained by SPSS 22.0 statistical software.Results:There was no statistical significance in the X coordinate values between left and right sides of the transverse temporal gyrus in males(P>0.05),while there was statistical significance in the Z coordinate values between left and right sides(P<0.05).There was no statistical significance in the X and Z coordinate values between left and right sides of the transverse temporal gyrus in women(P>0.05).The regression equation of Y value to X value of transverse plane in medial margin of transverse temporalis gyrus in right side and left side were Y=29.3-6.48X+0.25X2-0.002 5X3(P<0.01)and Y=-108-4.73X-0.05X2(P<0.01),respectively.The regression equation of Z value to Y value of sagittal plane in medial margin of transverse temporalis gyrus in right side and left side were Z=-0.8-0.35Y-0.004Y2(P<0.01)and Z=0.1-0.2Y+0.008 64Y2-0.000 569Y3(P<0.01),respectively.The regression equation of Z value to Y value of coronal plane in medial margin of transverse temporalis gyrus in right side and left side were Z=54.8-2.63X+0.03X2(P<0.01)and Z=58.9+2.82X+0.03X2(P<0.01),respectively.Conclusions:It has great clinical value to construct stereotaxic data sets of the Heschl’s gyrus and linear regression equation for stereotaxic neurosurgery,interventional radiotherapy and minimally invasive neurosurgery in the lesions of the Heschl’s gyrus and its adjacent areas.It also great significance to reveal the morphological rule of the development of the heschl’s gyrus.
