1. A magnetic resonance (MR) method for the imaging of an object arranged in a steady magnetic fields comprising: exciting spins spins in a part of the object, measuring MR signals along a predetermined trajectory containing a plurality of lines in k-space by application of a read gradient and other gradients, applying both a navigator gradient for the measurement of navigator MR signals and an additional gradient in order to achieve diffusion sensitivity of the MR signal, determining phase corrections for the measured navigator RM signals so ag to orient the measured navigator MR signals, wherein the phase corrections are determined at measuring points where the moduli of measured navigator MR signals are smaller than a threshold value, and wherein the ease corrections are determined from the phases of measured navigator MR signals at different reference measuring points where the moduli exceed the threshold value, determining phase corrections from phases and moduli of the corrected navigator MR signals so as to correct the measured MR signals, and determining an image of the part of the object from the corrected MR signals.
