磁共振波谱成像(magnetic resonance spectroscopy,MRS)是基于核磁共振的原理发展起来的,因其可对脑组织内各种代谢物的化学浓度进行体外测量,现已成为一种重要的无创性检测活体组织的生化特性及代谢变化的诊断工具。目前,国内外MRS的功能研究已成为热点[1],但在放射性脑损伤研 Magnetic resonance spectroscopy (MRS) was developed based on the principle of nuclear magnetic resonance (MRS), because it can measure the chemical concentration of various metabolites in brain tissue in vitro and has become an important noninvasive test organism Tissue biochemical characteristics and metabolic changes in diagnostic tools. At present, the research on the function of MRS at home and abroad has become a hot spot [1], but in the research of radioactive brain injury
