Computer-implemented method for evaluating magnetic resonance data, magnetic resonance device, computer program, and electronically readable data medium

A computer-implemented method is described for evaluating magnetic resonance data of a scan region of a patient acquired by means of a magnetic resonance device, wherein, following acquisition of at least two image datasets using an acquisition technique at different echo times in each case, by combination of the image datasets, at least two combination datasets, each showing magnetic resonance signals of a different spin species, are determined, wherein, in order to assign a spin species shown in the combination dataset to each combination dataset, an input dataset is determined from the combination datasets, and the input dataset is evaluated by means of an assignment algorithm which comprises a trained function and which determines assignment information assigning to each combination dataset the spin species shown therein, wherein a pre-trained function trained further with regard to the spin species assignment by means of transfer learning is used as the trained function.
