人体侧脑室容量年龄变化的研究

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岁期间侧脑室任人唯贤一无显著性差异；（３）９月－９０岁的蓁各年龄组之间的侧脑室容量均存在显著性差异。

STUDY ON CHANGES IN THE VOLUME OF NORMAL LATERAL VENTRICLES DURING AGING

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.
