A method of MR imaging and spectroscopy to reduce artifacts occurring due to the motion of an object to be represented, wherein the object position is determined quasi-continuously during the runtime of the MR acquisition, which includes one or more partial acquisitions (TA), and wherein motion correction is performed, which comprises dynamic adaptation of the frequency and phase settings of the RF system of the tomograph and of the orientation and amplitudes of the gradients during the runtime of the MR acquisition according to the current object position. The motion correction is thereby applied during a signal weighting period, during a signal read-out period, or between and/or during the two stated periods and the adaptations for motion correction are performed without interrupting or slowing the temporal progression of the MR acquisition. In this way, artifacts due to motion of the object to be represented can be further reduced.
