External Email - Use Caution
Hi Doug, thank you for the response. I would appreciate if you advice any
better method to compute the SNR for PET signal within an ROI (e..g. thalamus)?
I used spmregister to move my PET images to Freesurfer space then I am thinking
of using mri_segs
Yes, but know that the "SNR" as computed there is the spatial mean
divided by the spatial standard dev. This is likely not the SNR that you
want

Hi Freesurfer team,
I would like to use "mri_segstat" to compute SNR for regions of interest. My
question is, if I use PET images as input does this mean that SNR will be
computed for the PET signal in the ROIs?
Thanks for any help
