I'm not sure what you are trying to get. voxel volume or SUVR?External Email - Use Caution
Thank you, Dr. Greve
I checked all about your comment.
I have questions more.1. I found that volumes or counts in gtm.stats.dat are for native PET space.If co-registered PET onto corresponding MRI(i.e. MRI space) is available using rbv.nii.gz from mri_gtmpvc,
Or if you recommend it by gtm.stats.dat, I can use gtm.stats.dat --rescale (reference regions) for SUVR in PET space.What do you prefer or recommend?
The RBV is in anatomical space, if you want to map it back to pet space, you need the registration file in the aux folder (not --regheader).
2. I used mri_vol2vol --mov rbv.nii.gz --targ original_PET.nii --o test.nii --regheaderbecause rbv.nii.gz is in different space.but when overlaid with them, registration is not correct. (WHY)rbv.nii.gz is in different space, even not in T1.mgz space. (DKT space)I just wanted to use the pv-corrected image for image processing.and you also said, smoothing is required after PVC. (Surface or volume based smoothing (resonable).
