Dixon’s fat/water separation method offers fat suppression based on chemical shift, insensitive to main field inhomogeneity, which is desirable in musculoskeletal MRI when imaging off-center, at anatomical sites with strong patient induced field inhomogeneity, or near metallic implants. A single acquisition additionally yields non fat suppressed and fat only-images, providing additional information that can potentially replace conventional images, in particular imaging both with and without spectral fat saturation. The method is compatible with both spin echo and gradient echo sequences with various contrast weighting. The prolonged acquisition time comes with increased SNR, providing capacity for compensation using other acceleration techniques.
