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.
对123名年龄在23岁至88岁的正常受试者进行了与衰老相关的头颅计算机断层扫描变化研究。半卵圆中心白质的衰减值随年龄增长而降低。排除年龄影响后,脑室和脑沟大小对衰减值没有独立影响。这一发现表明,随着年龄增长,白质的化学成分可能会逐渐发生变化。
