Application of magnetic resonance spectroscopy( MRS )in the clinical diagnosis has become popular, since spectroscopic analysis can show changes in biochemical information, reflect tumor pathology at the molecular level, it can help clinicians to identify diseases. Because MRS is a non-invasive method and without radiation damage,it provides the necessary support for repeated examinations in order to monitor efficacy of radiotherapy and chemotherapy,and it can greatly reduce patients' psychological and physiological burden. Here is mainly to introduce MRS technological points and ' H-MRS application in identification of breast tumors.%磁共振波谱(MRS)在临床影像诊断中的应用越来越普及,通过波谱分析来显示病灶生化信息的改变,能在分子水平上反映肿物的病理情况,为临床医师鉴别病变提供影像依据,同时由于MRS的无创性和无射线损害,为反复检查以监测放化疗效果提供必要的影像支持,大大减轻了患者的心理和生理的负担.在此主要阐述MRS技术重点介绍1H-MRS技术及其在鉴别乳腺病变中的应用.
