Abstract

In a method and apparatus for determining the fat content of the liver of a patient using measured spectral magnetic resonance data, wherein a first contribution to the spectral magnetic resonance data is based on fat, a second contribution to the spectral magnetic resonance data is based on water and on a further substance, a frequency range that forms the basis of the spectral magnetic resonance data is subdivided at least into a first subrange and into a second subrange, the second contribution is approximated using the spectral magnetic resonance data from the second subrange. The first contribution is determined taking into account the spectral magnetic resonance data and the approximation of the second contribution. The fat content is determined on the basis of the first contribution.
