Hi,
We are at the start of a study on TBI, in which we’re obtaining MEMPRAGE and T2-SPACE-FLAIR images (the images are obtained in Lunder 6 scanner, and I wonder if I can find T1 & FLAIR matched sequences for morphormetry on that scanner). The pixel size of the MEMPRAGE sequence is 1mm isotropic, while the one for T2-SPACE-FLAIR is 0.5 x 0.5 x 1mm; they’re not bandwidth matched either (I’ve attached the details of the sequences we’re using). I just wanted to know if we should make changes to our T2-SPACE-FLAIR sequence and match it with the MEMPRAGE sequence to feed the FLAIR images into recon-all for dura correction, or if we should leave the T2-SPACE-FLAIR sequence as it is and use the four echoes of MEMPRAGE for dura correction (I mean, is dura correction using different echoes of MEMPRAGE as good as feeding FLAIR images into recon-all?)
Thank you very much, Emad
