2D T2-weighted turbo spin-echo (T2w-TSE), fluid attenuated inversion recovery (FLAIR) with and without fat suppression are widely used in the clinical brain and spine protocols to improve diagnosis. However, FLAIR suffers from low SNR and long scan times. In this work, we developed a dual-acquisition 3D TSE sequence combined with dual-echo Dixon based approach to generate T2-weighted and FLAIR images of the spine with and without fat suppression in a single acquisition using the similar acquisition time as 2D FLAIR. Uniform fat/water separation was achieved using a shared-field-map and complex subtraction was used to generate FLAIR-like images without artifacts.
