氢质子波谱在阿尔茨海默病中的价值

Objective To study the diagnosis value of proton magnetic resonance spectroscopy(1H-MRS)in Alzheimer disease(AD).Methods Using stimulated echo acquisition mode,29 AD patients and 20 elderlv healthy ones as control group were underwent with Magnetic ResonaJlce Spectrum (MRs)examination in hippocampus,temporal parietal cortex and cingulate gyrus,the metabolites of MRS were analvzed to have N-aeetyl aspartate(NAA),creatine(Cr),choline(Cho),myo-inositol (mI),and comDarle the ratio of each other as well as the difference between the two groups.Rmulta NAA of AD patients in hippocampus,temporal parietal cortex and ringulate gyrus were(0.40±0.06),(0.42±0.06),(0.43±0.08),respectively, and have no significant difference to the healthy group(P＞0.05);mI were(0.25±0.08).(0.23±0.06),(0.21±0.05),respectively,and have significant difference to the healthy group(P＜0.05):NAA/Cr werle(1.30±O.10),(1.40±0.11),(1.42±0.12),respectively,and have no significant differenoe to the healthy group(P＞0.05);mI/Cr were,(0.81±0.07),(0.78±0..08),(0.70±0.06),respectively,and have significant difference to the healthy group(P＜0.05);mI,NAA were(0.61±0.06),(0.55±0.08),(0.49±0.07),respeetively,and have significant difference to the healthy group(P＜0.05).In AD patients,NAA,NAA/Cr decrease and mI,mI/Cr,mI/NAA increase,and the value in hippocampus＞temporal parietal cortex＞cingulate gyrus.Conclusion The changes of MRS in AD patients,mainly reflected a decline in NAA and rise in mI,which has some reference in the diagnosis in AD.
