【摘要】：目的探讨老年人杏仁核三维形心的坐标界定及其在临床上的应用。方法对数据库中无肉眼可见器质性病变的100例大脑磁共振成像(MRI)图像进行三维重建。建立恰当坐标原点,测量杏仁核的上下径、左右径、前后径的数值,同时测量杏仁核各形心的三维坐标数据和视束与杏仁核的距离。结果三维重建图像轮廓清晰、方便测量;确定外侧裂距大脑侧脑室颞角最前缘最近的点为坐标原点,通过坐标平移,得到杏仁核各形态学参数及各形心的坐标值。杏仁核的上下径、左右径、前后径测量指标r1、r2、r3的左右测量值和男女测量值比较差异均无统计学意义(P0.05);通过杏仁核各形心三维坐标值计算出的球坐标数据(R,θ,φ),前后径形心球坐标数据值R左右比较时有统计学意义(P0.05),男女数据值比较均无统计学意义(P0.05);杏仁核不同层面与视束的距离h1、h2、h3、h4、h5、h6和h7左右数据值比较无统计学意义(P0.05)。结论杏仁核的三维坐标重建是人体数字化工程的一部分,其各参数的测量为临床杏仁核毁损术提供了重要的理论依据。
[Abstract]:Objective to explore the coordinate definition of three-dimensional centroid of amygdala in the elderly and its clinical application. Methods three-dimensional (MRI) images of 100 cases of brain MRI without visible organic lesions in the database were reconstructed. The proper coordinate origin was established to measure the upper and lower diameter, left and right diameter, anteroposterior diameter of the amygdala, and to measure the three-dimensional coordinate data of each center of the amygdala and the distance between the visual bundle and the amygdala. Results the contour of 3D reconstruction image was clear and easy to measure, and the nearest point from the lateral fissure to the anterior edge of the temporal horn of lateral ventricle was determined as the coordinate origin. The morphologic parameters and coordinate values of the centroid of the amygdaloid nucleus were obtained by coordinate translation. The upper and lower dimensions of the amygdala, the left and right diameters, There was no significant difference between the left and right values of the anteroposterior diameter measurement index r1 / R2 / R3 and the values measured by men and women (P0.05), and the spherical coordinate data (R, 胃, 蠁) calculated from the three-dimensional coordinates of the nucleus amygdala (R, 胃, 蠁), the ratio of the values of the spherical coordinates of the anterior and posterior diameter of the spherical coordinates to the values of the spherical coordinates of the anteroposterior diameter (R, 胃, 蠁) There was statistical significance (P0.05), and there was no significant difference between male and female data (P0.05); the distance between different layers of amygdala and visual tract was not statistically significant (P0.05), and the distance between different layers of amygdala and visual tract was not statistically significant (P0.05). Conclusion Three-dimensional coordinate reconstruction of amygdala is a part of human digital engineering, and the measurement of its parameters provides an important theoretical basis for clinical amygdalotomy.
