Hi, Is there a way to address or account the effects of partial voluming when sampling grey matter intensity (mri_vol2surf)?
In particular, where there is cortical thinning, I'm also finding intensity changes that could either be due to changes in the amount of partial voluming or a change in the grey matter tissue contrast. Is there any way to disambiguate the two? The commands I'm using are: bbregister --s "$s" --mov "$s" --mov "$s"/mri/brainmask.mgz --reg "$s"/mri/transforms/Identity.dat --init-fsl --t1 mri_vol2surf --src "$s"/mri/brainmask.mgz --out "$s"/surf/"$h".T1_intensity.mgh --srcreg "$s"/mri/transforms/Identity.dat --hemi "$h" --projfrac 0.2 Thanks, Konrad _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
