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_segstat to generate SNR for the PET signal within an ROI, would
you please suggest an efficient way to do it?
Thank you!
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
