摘要：

目的　对立体定向脑图谱的基准点进行测定研究，为构建临床立体定向脑手术提供基础。方法　在立体定向空间坐标系内，应用MR扫描图像处理技术对120例健康自愿者和应用解剖学技术对30例尸脑分别进行脑内基准点前连合（AC）、后连合（PC）的径值和前后连合间距（ICD）进行测量。结果　在立体定向空间内，无论在大体标本，还是在MR图像上，AC、PC均清晰可见；在尸脑上测得AC的前后径为（2.75±0.76）mm，上下径为（3.85±0.68）mm，PC的前后径为（1.87±0.58）mm，上下径为（2.48±0.64）mm，ICD长度为（22.68±1.46）mm；在健康自愿者测得AC的前后径为（2.80±0.32）mm，上下径为（3.82±　0.37）mm，PC的前后径为（1.76±0.30）mm，上下径为（2.30±0.45）mm，ICD长度为（23.84±1.32）mm。结论　通过尸脑与健康正常人脑的对比测量研究，在立体定向坐标系内脑内AC、PC是脑内准确定位的基准点，　AC-PC是恒定的参考线。

Abstract:

Objective　To measure the reference point of stereotactic brain in order to build morphological data for stereotactic brain atlas and stereotactic brain surgery.　Methods　The brain reference points of AC diameter, PC diameter and ICD length in stereotactic coordinate system were measured from 120 healthy volunteers using modern imaging techniques and 30 corpses using traditional anatomical techniques and then compared with each other.　Results　In stereotactic space AC and PC were seen clearly both in specimens and in MR imagines. The AC value in dead brain was（2.75±0.76）mm in anteroposterior diameter, （3.85±0.68）mm in vertical diameter, the PC value was （1.87±0.58）mm in anteroposterior diameter and （2.48±0.64）mm in vertical diameter and ICD length was （22.68±1.46mm）. While in healthy volunteers the AC value was （2.80±0.32）mm in anteroposterior diameter and （3.82±0.37）mm in vertical diameter, PC value was （1.76±0.30）mm in anteroposterior diameter and （2.30±0.45）mm vertical diameter, but the ICD length was（23.84±1.32）mm, respectively. 　Conclusions　AC and PC are accurate reference points in stereotactic coordinate system and AC-PC is a constant reference line in brain.
