In a method to determine a phase position of a magnetization that is caused by radiation of an adiabatic RF pulse for the acquisition of magnetic resonance signals from a slice of an examination subject, an RF pulse of a first type is radiated and a first magnetic resonance signal is acquired, an adiabatic RF pulse is radiated and a second magnetic resonance signal is acquired, the phase of a magnetization induced by the RF pulse of the first type is calculated, as a first phase, and the phase of a magnetization induced by the adiabatic RF pulse is calculated as a second phase, and the phase position of the second phase in relation to the first phase is determined.
