Previously-published fast spin echo (FSE)based Dixon techniques for water and fat separation all require multiple scans and often a substantial increase in the echo spacing (esp). In this work, we developed a novel fast spin echo triple echo Dixon (fTED) technique which acquires three raw images in a single scan with readout gradients of alternating polarity and practically no increase in esp. We demonstrate that these three raw images can be used to generate separate water-only and fat-only images and thus allow for high-quality fat-separated T2-weighted imaging of an entire abdomen in only two breadth holds.
