| 中文摘要: |
| 目的 探讨颞叶磁共振质子波谱(1HMRS) 的研究方法及正常中国人脑内物质含量的正常范围。方法
对30 例健康人进行1HMRS 研究,观察NAA、Cr 和Cho 等各代谢产物波峰的特点,并对NAA/ Cr + Cho ,NAA/ Cr 及
Cho/ Cr 各比值进行定量分析。结果 颞叶脑组织内NAA 峰高于Cr 峰和Cho 峰。NAA/ Cr + Cho 、NAA/ Cr 和Cho/
Cr 双侧没有显著性差异。结 |
| 英文摘要: |
| Purpose To discuss the method of 1HMRS in temporal lobe and establish the normal range of the metablelic
value in Chinese people. Methods 30 healthy volunteers underwent 1HMRS study on 2. 0T MRI/ MRS system. Signals of
NAA ,Cr and Cho were observed ,Ratios of NAA/ Cr + Cho ,NAA/ Cr and Cho/ Cr were calculated. Results The signal
from NAA was higher than that from Cr and Cho. There was no significant difference of NAA/ Cr + Cho ,NAA/ Cr and
Cho/ Cr between two temporal lobes. The mean NAA/ Cr + Cho ratio was 0.72 , the lower limit of NAA/ Cr + Cho was
0.60. Conclusions MRS is a new noninvasive method for biochemistry study of human brain. The determination of normal
range of NAA/ Cr + Cho provided a standard for detecting metabolic abnormality in temporal lobe epilepsy. |
