Re: [Freesurfer] using T2* weighted scans to assist with dura stripping in a GE scanner?
Hi Matt, Thanks for the link. Reading on pages 29-31, I am struck by the complexity of the procedure. Not to say that it doesn't work, or that the single T1w image free-surfer stuff is simple :-), on the contrary, it's just that I was expecting to see something about an optimization that used both images, rather than something based on the T1w image followed by an exclusion criterion based on the T2w image. Anyway, works better than without. Minor question on the acquisition of the anatomicals: - Why are you using partial fourier in the read direction? You're throwing away a lot of SNR at the high spatial frequencies, seems a shame to go to 0.7mm and then do that.

Re: [Freesurfer] using T2* weighted scans to assist with dura stripping in a GE scanner?
Gordon Xu who helped us set up the protocol reminded me of the following: The main benefit of the readout PF is to reduce echo spacing, hence less blurring in the slice direction. The side benefit is that it also reduces the minimum TE, hence less dropout. However, you do give up some SNR at the high spatial frequency as Souheil mentioned. There are two senarios of this, a) the SNR is adequate, you only lose some SNR due to less sampling, b) if the SNR is borderline or worse, in addition to losing SNR you also lose some spatial resolution in the readout direction as the other side of the high spatial frequency k-space is less reliable. I remember we did pilot acquisition with and without asymmetric echo in two subjects. You looked at the images and you either liked the one with asymmetric echo because of less blurring or at least indifferent between the two. So I assume with the Siemens 32ch coil we are in senario a) above. If I had to guess, we probably went with the readout partial fourier to reduce the dropout regions in the gradient echo MPRAGE and didn't see an obvious loss in resolution. Peace, Matt.

Re: [Freesurfer] using T2* weighted scans to assist with dura stripping in a GE scanner?
Thanks very much for your response, Bruce. We already collect T2 in our
scanner -- not sure about FLAIR. Is there a way for them to work
analogously with the mri_make_surfaces command (as outlined here)?:
FreeSurfer command to correct dura:
mris_make_surfaces–dura filename_%d.mgz
-${lastecho}
-aseg aseg.auto.mgz
-mgz
-sdir ${SUBJECTS_DIR}
-output _dura_1and${lastecho}
$({target} ${hemi}
where filename_%d.mgz refers to the four separated echoes of the MEMPRAGE
and lastecho = 4
Generates:
lh.pial_dura_1and4, rh.pial_dura_1and4,
lh.white_dura_1and4, rh.white_dura_1and4
Thanks again for your help!
