Quantitative in - vivo - spectroscopy using oversampling, water lines reference and adaptation to prior knowledge

摘要

The method of the magnetic resonance spectroscopy of a substance comprising the steps of:a) introducing an object in a magnetic field,b) generating and refocus a transverse magnetization, in order to echo signals to generate an echo time te,c) the stepwise incrementing of te for obtaining a 2d - data record, wherein a f1 - bandwidth is used, for which an oversampling disturbing side bands is sufficient water in a spectral region of interest, andd) processing the data set, in order to chemical shift frequencies and j - coupling frequencies along a f2 - axis and j - coupling frequencies along a f1 - axis to obtain.
