Hello PetSurfer experts,
We are using the cerebellum cortex as our reference region, but noticed that the SUVR values for lh/rh cerebellum cortex do not have a value of 1 (which is what we were expecting). The actual SUVR values are 1.31 for the lh and 1.35 for the rh cerebellum cortex. I attached the stats file (gtm.stats.dat) and below is the command we ran.
mri_gtmpvc --i regmean.nii.gz --reg regmean_template.reg.lta --psf ${FWHM} --seg ${MR_ID}/mri/gtmseg.mgz --default-seg-merge --auto-mask PSF+2 .01 --mgx .01 --rescale 8 47 -o regmean_gtmpvc_output
Let me know if you need any more details.
Thanks so much, Aylin
