| 目的 探讨1H 磁共振波谱(1HMRS) 研究正常成人脑的价值。方法 选择60 例健康成人。1 HMRS 采用
定点分辨波谱序列。结果 ①同年龄组一侧脑灰层的1HMRS 波幅排列次序无变化;不同年龄组同一部位1HMRS 波
形与波幅不同。②NAA/ CR 及Glu-n/ CR 随年龄的增长而上升,MI/ CR 随年龄的增长而下降,CHO/ CR 先下降后上
升。同年龄组从前至后 |

| Purpose To evaluate 1H Magnetic Resonance Spectroscopy ( HMRS) in the study of normal adult brain.
Methods Sixty cases of healthy adults were selected ,point resolved spectroscopy sequence was required for 1HMRS. Results ①No prominent difference of shape and peak arrangement was seen at the different ipsilateral site in the same age
groups ;while difference at the same site in the different age groups was present . ②The ratio of NAA/ Cr and Glu-n/ CR
was higher in senile age group ;while that of MI/ Cr was lower. The ratio of CHO/ CR was in low-to-high order with the difference of age. The ratio of NAA/ CR and MI/ CR was gradually lower from anterior to posterior part of the brain. ③Negative correlation of CHO/ CR with age was present in groups aged lower than 50 years old ;while correlation of CHO/ CR、
MI/ CR and Glu-n/ CR with age was present in groups aged greater than 50 years old. Conclusion 1HMRS plays an important role in the evaluation of biochemical changes in the normal adult brain. |
