本文研究了123例23 ~ 88岁正常人的头颅CT随年龄增长的变化。半卵圆中心白色物质的衰减值随年龄增长而降低。当排除年龄的影响时，心室和脑沟的大小对衰减值没有独立的影响。这一发现表明，随着年龄的增长，白色物质的化学成分可能会逐渐发生变化。
Changes on computed cranial tomography related to aging were studied in 123 normal subjects aged 23 to 88 years. The attenuation value of the white matter in the centrum semiovale decreased with age. When the effect of age was excluded, ventricular and sulcal size did not have an independent effect on the attenuation value. This finding suggests that there may be gradual changes in the chemical composition of white matter with aging.
