Abstract:

Objective To investigate the correlation between corpus striatum and hippocampus structure, and provide the morphological evidence and related measurement value for clinical imaging diagnosis. Methods Magnetic resonance images of 100 cases of adult heads without pathological changes were collected and divided into five groups falling into five age ranges : 16 ~ 25, 26 ~ 35, 36 ~ 45, 46 ~ 55, 56 ~ 65 years old, with 10 males and 10 females in each age range.  Parameters such as the area, the transverse and vertical diameter of the corpus striatum and hippocampus were obtained and underwent statistical analyses. Results After standardization of data,  the outcome of the single factor analysis of variance showed: There was no gender difference in striatum area; The sagittal diameter of caudate head, the hippocampus area, and the transverse and sagittal diameter of the hippocampal  structure exhibited gender difference ( female>male ); The width of the temporal horn of the male was larger than the female;The transverse diameter of the caudate nucleus head exhibited side difference (left>right),while the right putamen area and the sagittal diameter was greater than on the left. Pearson correlation analysis showed: The head of caudate nucleus area was negatively related with age and the distance between the temporal lobe hooks, but was positively related with the width of the temporal horn. The hippocampal area was positively related with the head of caudate nucleus area and the width of the temporal horn. Conclusion The adult corpus striatum shrank with the increase of age; There was correlation between the hippocampus structure and corpus striatum on the morphology. The right putamen area was greater than the left. The female hippocampus area was greater than the male. The width of the temporal horn can be used as common references indicators in morphological research of the striatum and hippocampus.
