In a method for controlling a magnetic resonance tomography system for a Magnetic Resonance Fingerprinting (MRF) measurement: a dictionary group including at least two dictionaries is provided/created, each of the at least two dictionaries containing a multiplicity of different intensity profiles with a specific sampling scheme; a preliminary recording of magnetic resonance tomography (MRT) measurements is created; a sampling scheme is determined/defined based on the preliminary recording; a dictionary is selected from the at least two dictionaries of the dictionary group based on the preliminary recording; and an MRF measurement is performed using the defined sampling scheme and an MRF evaluation based on the selected dictionary.
