A method is for performing an angiographic measurement and creating an angiogram of a body region of a patient in a magnetic-resonance system and a magnetic-resonance system for operating such a method. In an embodiment, the method includes acquisition of a body region division of the angiographic measurement into partial angiographic measurements displaying the measurement start times, the measurement duration and the measurement end times of the partial angiographic measurements changing the measuring time points definition of sequence parameters of the partial angiographic measurements based on the changed measurement start times and/or measurement end times such that the partial angiographic measurement is performable between the associated measurement start time and measurement end time provision of the sequence parameters of the control unit of the magnetic-resonance system performance of the partial angiographic measurements and creation of the angiogram using the partial angiographic measurements performed.
