摘要
目的 :探索国人胼胝体在生长发育及老化过程中的形态学改变。材料与方法 :对 2 3 3例 2 80正常人进行磁共振检查 ,采用AUTOCAD软件对大脑正中矢状面的胼胝体进行总面积及分区面积的测量 ,采用SPSS软件进行统计学处理。结果 :2～ 1 8岁其间胼胝体总面积和分区面积随增龄而增大 ,1 9～ 5 0岁期间保持不变 ,5 0岁以上C2 分区面积减少。男性胼胝体大于女性。结论 :发育期间胼胝体随增龄而增大 ,国人胼胝体最快增长期较外国人提前 ;成年后保持不变 ,5 0岁以上C2 分区萎缩。
Objective:To study the changes in callosal morphology in development and aging.Methods:MRI examination was performed on 233 cases of 2 18 years old healthy person.Using autoCAD software,we measured the total area and subregion areas in sagittal MRI slice that best represented the midsagittal section.Statistic analysis was taken with SPSS for windows.Results:The total callosal area and 5 subregion areas increased with age from 2 to 18 years old,and remained constant during 19 to 50 years old.Area of C 2 subregion declined after 50.Male had larger total callosal area and subregion areas than female.Conclusion:Corpus callosal develops with age before aged 18 and remains constant in adults.The quickly developing period is early in Chinese than foreigner.Subregion C 2 atrophy after 50.Male has larger corpus callosal than female.
