An echo signal is generated in the presence of a readout magnetic field gradient in each time interval (TR) between successive RF pulses, with the echo time varying between at least a first value (TE1) associated with a first acquisition (ACQ1) and a second value (TE2) associated with a second acquisition (ACQ2). The invention proposes that at least one of the magnetic field gradients preceding and/or succeeding the readout magnetic field gradient in each time interval (TR) is temporally shifted, varied in duration and/or varied in amplitude between time intervals (TR). In this way, a reduction of the acoustic noise generated by the multi-acquisition Dixon sequence and, thus, of the discomfort for patients undergoing a corresponding examination is achieved. The echo signals are recorded and an MR image is reconstructed with separating signal contributions from water and fat based on the recorded echo signals of the at least two acquisitions (ACQ1, ACQ2). Moreover the invention relates to an MR device (1) and to a computer program to be run on an MR device (1).

METHOD OF PREDICTING A FIELD PERTURBATION MAP FOR MAGNETIC RESONANCE IMAGING
Proposed concepts thus aim to provide schemes, solutions, concepts, designs, methods and systems pertaining to predicting a field perturbation map for magnetic resonance imaging (MRI) of a subject. In particular, the invention aims to provide a field perturbation map of the subject without the need for additional time-consuming scans of the subject. An accurate field perturbation map is necessary in order to obtain an MRI scan of the subject of high quality. Accordingly, a synthetic computed tomography (CT) image is generated by inputting an initial MRI magnitude image of the subject to an image conversion machine learning algorithm. Subsequently, a weighted susceptibility map of the subject is determined based on the synthetic CT image and the initial MRI magnitude image, which is in turn used to determine the field perturbation map of the subject.
