【摘要】 在135例正常人体头颅CT扫描图像上运用体视学方法研究了侧脑室容量的年龄变化.结果为:(1)侧脑室的容量随年龄的增长而逐渐增大,50岁以后容量显著增大;(2)9月～10岁组与11～20岁组之间,51～60岁组与61～70岁组之间,21～50岁期间侧脑室容量无显著性差异(P值均大于0.05);(3)9月～90岁的其余各年龄组之间的侧脑室容量均存在显著性差异(P<0.05).更多还原

【Abstract】 Using a simple stereological method, we estimated the lateral ventricular volume in 135 normal subjects from 9 months to 90 years of age based on CT scans. The results were as follows: (1) A gradually progressive increase in lateral ventricular volume from the first through fourth decades was followed by a dramatic increase in the fifth decade. (2) The increments of increase between the first decade and second decade were not statistically significant, so were the increments of increase between the fifth decade and sixth decade. There were no significant age differences in the volume during twenty one to fifty years. (3) All other increments of increase between decades were significant.更多还原
