Abstract:  Objective To investigate the clinical effect of magnetic resonance spectroscopic imaging technique in diagnosis of central nervous system disease. Methods Using comparative analysis, literature analysis, and questionnaire survey to analyze the research data. Results Lactic acid peak value of magnetic resonance spectroscopy region in delayed edema area of patients with cerebral hemorrhage was changed and NAA/Cr value was decreased, which indicated that this region was of severe ischemia and neurons had been damaged. Results of cerebral infarction research which used rats as experimental objects showed that NAA value was declined constantly and finally disappeared as time extended. Diagnostic results of patients with Parkinson's disease showed that hippocampal NAA/Cr value in substantia nigra of control group was much higher than that of experimental group. Pathological changes of Alzheimer's disease can be found timely by using magnetic resonance spectroscopic imaging technique. Diagnostic results of patients with MS's diseases showed that NAA value had been decreased. Conclusion The condition of patients with cerebrovascular and neural degeneration diseases can be determined timely by using magnetic resonance spectroscopy so that patients can get timely diagnosis and treatment.
