Imaging and sectional anatomy of corpus striatum
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.
