This work demonstrates 3D respiratory motion-corrected and cardiac resolved fat-water separation in the human body at 7T. Accurate fat fraction quantification using bipolar readout gradients was validated in a phantom. The impact of motion compensation on the underlying motion resolved $$$\Delta\text{B0}$$$ maps is investigated and estimated. In total the 3D fat-water separation and fat fraction quantification is successfully demonstrated in 10 healthy volunteers at 7T with a large BMI range from $$$19$$$ to $$$34 \text{kg/m}²$$$.
