We investigated a motion immune Dixon TFE approach incorporating a 3D radial stack-of-stars acquisition module interleaved with a spiral excitation navigator to gate and track the acquisition. Image quality, sharpness and streaking artifact level and its variability over different patient breathing patterns is efficiently improved to an extent where it is preferred over the state-of-the art breath hold (BH) Dixon scans. Next to that, it allowed scan time reductions of 30% in average. This technique provides motion-free, high resolution hepatic imaging with the benefits of Dixon providing consistent good fat suppression over a large FOV with water, fat, IP and OP diagnostic information all-in-one scan.
