Re: [Freesurfer] Adding low-res T2 and PD images in the recon-all stream - any advantages?

Hi Gari

we use a bandwidth and readout matched (to our multi-echo mprage) T2-SPACE with a FLAIR inversion pulse. Andre (ccd) can give you the details

Hi Bruce,is there any recommended protocol for T2 acquisition to be used in the 5.2 recon-all stream?

Should we used the same voxel size as the T1? (we are using  1 mm3 right now).

If it is going to improve the skull striping and pial surface creation, we might acquire specific T2 images just to be used in the recon-all stream.

many thanks, Gari

  the T2 might in 5.2, but it is pretty thick slices so might hurt more
  than it helps. Not sure, but you can try it out
