摘要：

目的　探讨断面与MRI纹状体的变化规律及其意义。方法利用31例成人头部横断面标本及50例活体MRI扫描，观测纹状体及其相关结构，所得数据进行标准化处理。结果断面标本纹状体面积存在性差(女性>男性)；MRI成像显示纹状体面积无性差，苍白球面积存在侧差（左>右）。纹状体及其相关结构的数值在断面与MRI上表现趋势基本一致。在断面与MRI上端脑面积与纹状体面积呈正相关；尾状核头面积在断面上与背侧丘脑面积呈负相关，在MRI上与壳核面积呈负相关；侧脑室前角的距离在断面上与壳面积呈负相关，在MRI上与尾状核头面积呈正相关。结论 MRI可较好地反映纹状体及其相关结构的情况；纹状体相邻结构的变化可作为研究其形态变化的参考指标；数据标准化可有效排除个体差异的干扰。

Abstract:

Objective　To discuss anatomic features of corpus striatum on cross section and MRI data. Methods　31 cross-sectional specimens of adult head and 50 cases of MRI data were used in this study. Corpus striatum and its related structures were observed and analyzed.　Results　For striatum area, there was gender difference on cross-sectional specimens (women>male); but there was no difference on MRI data. On the contrary, bilateral areas of globus pallidus were different on MRI data (left > right). Other anatomic parameters of striatum and its related structures had no difference between sections and MRI data. The area of telencephalon positively related to that of striatum, regardless of cross-section or MRI. The head area of caudate nucleus was negatively related to dorsal thalamus area on cross-section, and negatively related to putamen area on MRI. The distance of anterior horn of lateral ventricle was negatively related to the putamen area on cross-section, but positively correlated with the head area of caudate nucleus on MRI.　Conclusions　MRI can better reflect the striatum and its related structures. The changes of the adjacent structures can be used as a reference for exploring morphological changes of corpus striatum.
