摘要
目的研究健康中国人脑立体定向标志前连合（AC）、后连合（PC），为立体定向功能神经外科提供基础数据。方法采集健康中国成人自愿者脑MRI图像120例，男女各60例。在正中矢状面上分别测量AC、PC的宽度和AC—PC的长度（LI），采用统计学方法分析LI与年龄的相关性及性别差异．并将颅长纳入比较。结果LI的长度在19．70-25．65mm之间，平均为（22．92±1．13）mm；AC、PC平均宽度分别为（2．30±0．37）mm、（1．60±0．31）mm；本组中国成人各年龄段组人脑LI长度与年龄无相关性．男性LI长度大于女性，差异有统计学意义（P〈0．05），将颅长纳入比较后，这种差异性消失了：AC、PC的宽度与年龄无相关性，AC的宽度女性大于男性，PC的宽度性别差异无统计学意义。结论立体定向功能神经外科中AC-PC线是稳定的脑内结构测量参考线。
Objective To provide fundamental information and data for stereotactic and functional neurosurgery through studying the characteristic anterior commissure （AC） and posterior commissure （PC） ofstereotaxy for healthy Chinese brains. Methods Brain MR images of 120 healthy Chinese adult volunteers were acquired; half of them were males. The respective width of AC and PC and the length of AC-PC （LI） were measured in the medial sagittal plane; the gender difference of Ll and its correlation with age were analyzed; the cranial length was also included for comparison. LI was analyzed between males and females and t-test was applied to assess the widths of AC and PC. Results LI was between 19.70 and 25.65 mm, with the mean value of （22.92±1.13） mm; the width of AC and PC was respectively （2.30±0.37） mm and （1.60±0.31） mm. There was no correlation between LI and age among age groups of Chinese adults; LI of males were longer than that of females, but the difference vanished after the cranial length was included for comparison. There was no correlation between the widths of AC and PC and age; the AC width of females was longer than that of males, but there was no gender difference in the width of PC. Conclusion AC-PC line is a stable reference line for the measurement of intraeranial structures in stereotactic and functional neurosurgery.
