a pulse and gradient sequence of a variant of the inventive method phase encoding is performed at a later time compared to the gradient sequence of fig2 such that after irradiation of the rf pulse 1 the spins are rephased using a rephasing gradient pulse 2 u2032 the development of the system magnetization is observed or recorded during the rf excitation and phase encoding navigator scan the region 4 a of successive data points indicator signal of this recording may serve as an indicator for the respective motion state of the object during the corresponding individual measurement in the inventive method region 4 a of fig3 is selected such that the successive data points of this region 4 a are recorded with a rephased nuclear spin system the navigator scan is followed by phase encoding and reading out of the echo signal in order to reduce the duration of the individual measurement the region 4 b may be selected as indicator whose successive data points were already recorded during rephasing of the spins in response to the rephasing gradient pulse 2 u2032 fig4 the navigator scan is therefore terminated at an earlier time such that phase encoding and reading out of the echo signal may also.
