摘要:
This article reviews spectral editing techniques for in vivo H-1 NMR spectroscopy of human brain tissue at moderate field strengths of 1.5-3 Tesla. Various aspects of H-1 NMR spectroscopy are discussed with regard to in vivo applications. The parameter set [delta, J, n] (delta being the relative chemical shift, J the scalar coupling constant and n the number of coupled spins) is used to characterize the spin systems under investigation and to classify the editing techniques that are used in in vivo H-1 NMR spectroscopy.
