Abstract

In a method and apparatus for detection improvement of a weakly-sensitive atomic nucleus type in MR spectroscopy data acquisition using polarization transfer for a strongly-sensitive atomic nucleus type (A) with involvement of an MR-active, weakly-sensitive atomic nucleus type (X), all RF pulses are radiated sequentially, i.e. with defined time interval relative to one another, such that at no point in time of the sequence are different RF pulses radiated simultaneously or overlapping, and the sequence of the RF pulses causes a polarization transfer of the two involved atomic nucleus types (A), (X).
