摘要： 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.

摘要： In a device, method and computer program product for generation of an exposure plan for irradiating a patient, at least one reference data set independent of the patient is provided, from which an attenuation of high-energy radiation upon passage through a reference body can be determined. A patient magnetic resonance image of the patient is adapted using the reference data set and an exposure plan is generated based on the patient magnetic resonance image and the patient-specific attenuation of high-energy radiation upon passage through the patient. The patient-specific attenuation of high-energy radiation upon passage through the patient is determined using the adaptation of the patient magnetic resonance image with the reference data set.

摘要： In a magnetic resonance spectroscopy method, an excitation RF pulse is emitted with simultaneous emission of a first gradient during an excitation segment having a time duration corresponding to a transmission duration of the excitation RF pulse, a first refocusing RF pulse is emitted that has a first phase with respect to the excitation RF pulse with simultaneous emission of a second gradient during a first refocusing segment that temporally immediately follows the excitation segment and has a time duration corresponding to a transmission duration of the first refocusing RF pulse, an intermediate segment is allowed to elapse immediately temporally following the first refocusing segment for, among other things, temporal positioning of a secondary spin echo, a second refocusing RF pulse is emitted that has a second phase with respect to the excitation RF pulse, with simultaneous emission of a third gradient during a second refocusing segment immediately temporally following the intermediate segment and having a time duration corresponding to a transmission duration of the second refocusing RF pulse, the secondary spin echo is acquired during an acquisition segment immediately temporally following the second refocusing segment, and the aforementioned steps are repeated with a variation of phases of the RF pulses corresponding to a phase cycle.
