Spiral imaging promises high scan efficiency due to long readouts, but suffers from strong susceptibility to off-resonance effects. Water-fat imaging with chemical shift encoding provides exactly the information required for an off-resonance correction. The combination of both thus seems particularly attractive. In the present work, the software of a clinical scanner is modified and extended to provide a fully automated and integrated reconstruction, separation, and correction for spiral water-fat imaging in clinical applications. An initial evaluation in abdominal and cardiac imaging suggests that good image quality and acceptable processing times are achieved.
