Magnetic resonance spectroscopy (MRS) is an imaging technique that provides spectroscopic information about the changes of biological markers. Studies suggest that MRS can be helpful in the prognosis of patients with diffuse axonal injury (DAI)Methods: PubMed and Scopus as two major database were systematically searched in June 2015 by using following search strategy ((((Magnetic resonance spectroscopy OR MRS OR MR spectroscopy)) AND (Diffuse axonal injury OR DAI)) AND Prognosis) to find relevant articles in which the prognostic value of MRS had been investigated in patients with traumatic DAI. All necessary information were extracted and used for data synthesis based on the main purpose of this study. Of total 19 articles found in PubMed and 151 found in Scopus, 8 documents were selected for data extraction in several steps of article selection according to inclusion/exclusion criteria. Total number of patients participated in the selected documents was 197. All of the selected documents showed that MRS can be used for quantitative analysis of metabolite changes in patients with DAI.Discussion: The results of studies show that MRS imaging as a sensitive method can quantitatively determine even small variation of metabolites. Since any changes in metabolite level of the brain after traumatic injury may be useful in the prediction of patient’s outcome; therefore, if such sensitivity of MRS is proven, this method can have prognostic value in patients with DAI. Based on the concluded results of included articles, MRS as a sensitive tools is helpful in the prognosis of patients with DAI.

Introduction: Magnetic resonance spectroscopy (MRS) is an imaging technique that provides spectroscopic information on the changes in biological markers. Studies suggest that MRS can be valuable in the prognosis of patients with diffuse axonal injury (DAI).Methods: PubMed and Scopus, two major databases, were systematically searched in June 2015 using the following search strategy: ((((Magnetic resonance spectroscopy OR MRS OR MR spectroscopy)) AND (Diffuse axonal injury OR DAI)) AND Prognosis). Relevant articles were selected, and the prognostic value of MRS in patients with traumatic DAI was investigated. All necessary information was extracted for data synthesis based on the primary objective of this study.Results: Out of 19 articles found in PubMed and 151 in Scopus, eight documents were selected for data extraction following inclusion/exclusion criteria. The total number of patients included in the selected studies was 197. All selected articles demonstrated that MRS can be used to quantitatively analyze metabolite changes in patients with DAI.Conclusion: Based on the results of the included studies, MRS is a sensitive tool that can help predict the prognosis of patients with DAI.
