    • In a method for recording a magnetic resonance image with a magnetic resonance device, in which several projection image data records are recorded in succession with different gradient orientations, from which, through back projection, the magnetic resonance image is reconstructed, the recording of a projection data record in a recording time frame proceeds with a temporal frequency modulated excitation pulse of a pulse duration, wherein, through the frequency modulation of the excitation pulse, all spins to be recorded within the scope of the projection data record are excited in a temporal sequence and wherein the frequency modulation function describing the frequency modulation during the pulse duration exhibits at least one maximum and/or at least one minimum. During the excitation duration, a time-resolved reception signal is detected. The projection data record is determined from the reception signal through evaluation.

    • In a method to determine a kidney function parameter of kidneys of an examination person with the aid of magnetic resonance tomography, at least one magnetic resonance measurement is implemented for an examination region of the examination person that comprises a urinary bladder of the examination person, to acquire magnetic resonance data from the examination region that include at least image data. The concentration of a urophanic substance in the urinary bladder of the examination person is automatically determined based on the acquired magnetic resonance data. A volume of the urinary bladder is automatically determined based on the acquired image data. A kidney function parameter of the kidneys of the examination person is automatically determined on the basis of the determined concentration of the urophanic substance in the urinary bladder and of the specific volume of the urinary bladder.
