1. A computer-implemented method for automatically characterizing liver tissue of a patient, comprising:
receiving, via a first interface, a morphological magnetic resonance image data set and a magnetic resonance parameter map,
wherein the morphological magnetic resonance image data set and the magnetic resonance parameter map are each acquired via a magnetic resonance imaging device;
applying, via one or more processors, a trained function comprising a neural network to input data, the input data comprising the morphological magnetic resonance image data set and the magnetic resonance parameter map; and
providing, via a second interface, generated output data comprising a tissue score describing the liver tissue,
wherein the input data further comprises a magnetic resonance elastography data set of an imaging region comprising at least a portion of the liver tissue of the patient.
