磁共振波谱(MRspectroscopy,MRS)已经从研究阶段过渡到临床应用,使磁共振诊断深入到生化代谢水平。MRS是基于核磁共振现象和化学位移原理进行活体化学成分(或代谢产物)的无创测量技术。1概述MRS的原理在某些方面与MRI相同,要求短的射频脉冲以激励原子核,采集到的信号称为自由感
Magnetic resonance spectroscopy (MRS) has been the transition from the research phase to clinical application, so that the diagnosis of magnetic resonance depth to the level of biochemical metabolism. MRS is a noninvasive measurement technique for living chemical components (or metabolites) based on NMR and chemical shift principles. 1 Overview The principle of MRS is the same as that of MRI in some respects, requiring short RF pulses to excite the nuclei and the signals collected are referred to as a sense of freedom
