The conventional spin-echo (SE) sequence produces the best available T1-contrast and is often used for imaging of brain, head and neck, and spine. Unfortunately, the inclusion of fat suppression pulses in an SE acquisition substantially reduces the number of slices per TR and therefore the overall scan efficiency. In this work, we developed a flexible spin-echo triple-echo Dixon (flexible STED) technique that enables SE Dixon imaging with high efficiency. The feasibility of the technique is demonstrated with in vivo post-contrast fat-suppressed T1-weighted imaging of spine.
