External Email - Use Caution
Dear community,
I have tried the tutorial for PETsurfer. I would like to ask some
questions.
1) I have seen in the tutorial when you do PVC correction it is done
on PET dynamic raw data. Is this correct? Because I have seen some
tutorial where it is suggested on the motion corrected by AFNI image
so called pet.mc.nii.gz
If you are going to do motion correction, then you should do that before
PVC.
2) I also would like to compute hypometabolism on epileptic patients
based on a dynamic PET so called Patlak Kinetic modeling. Is that
possible with Freesurfer? I know there is Qmodeling toolbox in SPM but
I cannot get access to their toolbox (some issue about the download)
and I don’t know if there is another workaround.
I don't have patlak implemented in FS; I'll add it to the list.
If not possible to do Patlak with FreeSurfer is it correct to assume
the mean of the dynamic PET will provide epileptogenic zone for
epileptic patients based on FDG-PET as hypo metabolic regions?
I don't know
Sincerely,
Rene Andrade.
