Synthetic MR imaging is a method that can produce multiple contrasts from single sequence, as well quantitative maps. Our aim was to determine the feasibility of synthetic image for spine imaging.Thirty-eight patients with clinical indications infectious, degenerative, and neoplastic disease underwent an (11 cervical, 8 dorsal, 19 lumbosacral studies). The SyntAc acquisition time 5 minutes 40 seconds, added usual protocol consisting conventional sagittal T1 TSE, T2 STIR TSE.Synthetic T1-weighted, T2-weighted, images were adequate quality, 53% less than imaging. quality rated "good" both images. Interreader agreement concerning lesion conspicuity good Cohen κ 0.737. Artifacts white pixels/spike noise across contrast views, flow artifacts, more common in sequences, particularly STIR. There no statistically significant differences between readers scores assigned or conspicuity.Our study shows feasible produces, general, diagnostic confidence. Furthermore, non-negligible savings ability obtain measurements generate several should promise bright future routine.
