Claim 8:
9. A magnetic resonance (MR) device comprising at least one main magnet coil for generating a uniform, static magnetic field B0 within an examination volume, a number of gradient coils for generating switched magnetic field gradients in different spatial directions within the examination volume, at least one RF coil for generating RF pulses within the examination volume and/or for receiving MR signals from a body of a patient positioned in the examination volume, a control unit for controlling the temporal succession of RF pulses and switched magnetic field gradients, and a reconstruction unit for reconstructing MR images from the received MR signals, wherein the MR device is configured to perform a method including:
subjecting the body to an imaging sequence, which comprises at least one excitation RF pulse and switched magnetic field gradients, wherein a number of pairs of echo signals is generated at two different echo times (TE1, TE2) with different phase encodings to sample a region of k-space, and wherein the generation of each pair of echo signals is repeated during two or more different cardiac phases (AW1, AW2);
acquiring the echo signals from the body;
reconstructing phase images from the acquired echo signal data, wherein a phase image is reconstructed for each echo time and for each cardiac phase; and
reconstructing a final diagnostic image from the echo signal data using water/fat separation, wherein regions of at least one of flow or estimates of flow-induced phase errors are derived from the phase images to suppress or compensate for flow-induced leakage and/or swapping artifacts in the final diagnostic image.
