| 摘 要： | ４１例人脑活体Ｈ－１频谱，皆用ＰＲＥＳＳ技术加ＣＨＥＳＳ水抑制序列，完成于２．０特斯拉ＭＲＩ／ＭＲＳ（ｍａｇｎｅｔｉｃｒｅｓｏｎａｎｃｅｓｐｅｃｔｒｏｓｃｏｐｙ）一体化系统。其中健康志愿者（ｎ＝１４）的频谱较好地显示了包括：Ｎ－乙酰天门冬氨酸（Ｎ－ａｃｅｔｙｌａｓｐａｒｔａｔｅ）（ＮＡＡ）；γ－氨基丁酸（ＧＡＢＡ）；谷氨酸盐（Ｇｌｕ）；谷酰胺（Ｇｌｎ）；磷肌酸／肌酸（Ｐｃｒ／Ｃｒ）；胆碱（Ｃｈｏ）；肌醇（Ｉｎｓ）；萄萄糖（Ｇｌｃ）等脑代谢产物的共振峰。其余来自不同病例（ｎ＝２７）的频谱和健康人的相似，但共振峰的强度各有差异，表现了不同特点，对此笔者也作了较详细的分析讨论。

| Abstract: | cases in vivo MR spectra were recorded from human brain with a 2.0 T MRI/MRS system. PRESS technique was used together with CHESS (water suppressed method). The spectra from brains of healthy volunteers show several resonances from NAA; GABA; Glu; Gln; Pcr/cr;Cho;Ins;Glc,et al. The spectra from patients with different disease gave different feature. This paper,Writer synthetic analysed these Chang. |
