In a method for determining a complex sensitivity factor of an RF reception coil, which is part of an arrangement of a number of RF reception coils of a magnetic resonance scanner, which are operates to simultaneously acquire magnetic resonance spectroscopy data, FID signals from a volume of interest are acquired simultaneously with each of the RF reception coils, and one of the RF reception coils is designated as a reference coil and its FID signal is designated as a reference signal. A complex sensitivity factor for each other RF reception coil is determined by minimizing the differences between a number of data points of its FID signal, weighted with the complex sensitivity factor, and the corresponding data points of the FID signal of the reference coil.
