Abstract

The purpose of this study is to measure the standard volume of the ventricle of normal Koreans in their 20s and 40s and find out difference in the volume of the ventricle according to age and gender. We collected MR brain images from 118 people in their 20s (male 58, female 60)and 100 people in their 40s (male 41, female 59), so a total of 218 people.For each of sagittal, coronal and axial sections, the ventricular part was segmented using automatic and manual methods, and the volume was measured. In order to observe difference according to age and gender and to observe the interactive effect between age and gender, two-way ANOVA was carried out using age (2 levels)and gender (2 levels)as independent variables. The average volume of the ventricle of Koreans in their 20 s was 16.2 [cm3]and that of Koreans in their 40s was 23.1 [cm3].The average volume of the ventricle of male Koreans in their 20s and 40s was 21.9 [cm3]and that of female Koreans was 17.5 [cm3].The volume of the ventricle was significantly larger in Koreans in their 40s than those in their 20s, and in male Koreans than n female ones. Moreover, the increase of the volume of the ventricle with age was significantly larger in male Koreans than in female ones. According to the results of measuring the volume of the ventricle of normal Koreans in their 20s and 40s, the volume was significantly different according to age and gender, and the increase of the volume of the ventricle with age was significantly larger in men than in women.
