We
evaluate a novel Dixon based FSE sequence (fTED) for spine imaging that efficiently
provides T2 weighted imaging with and without fat suppression in a single
acquisition. Compared to STIR images the fTED water images showed equal
homogeneity of fat suppression with less motion artifact, sharper anatomic
detail, and less susceptibility artifact. The T2 fTED images without fat
suppression were equivalent to T2 FRFSE images for lesion detection. FTED
provides T2 imaging of the spine with and without fat suppression with a 56%
savings in scan time compared to STIR and T2 FRFSE imaging.
