Imaging of many body regions is adversely affected by the chemical shift between fat and water. We propose a new method for simultaneous, separate imaging of fat and water in which multiband pulses are used to simultaneously excite fat and water at their characteristic resonance frequencies, and CAIPIRINHA in combination with parallel imaging to reconstruct separate images of the two species. The fat image is corrected for chemical shift displacement and either recombined with the water image or evaluated separately. The proposed method achieves reliable water-fat separation and complete elimination of the chemical shift artefact in musculo-skeletal and breast imaging.
