It is not PVC corrected. To do that, you'd have to use the --mgx or --rbv
Note that doing voxel-wise PVC is tricky because you have multiple
tissue types in each voxel. So you can keep the same resolution but
then you have to represent only one tissue type (mgx) or you have to
create a higher resolution output volume where the resolution is high
enough to resolve the tissue types into different volumes (rbv).

Dear team,
I am using mri_gtmpvc to obtain PVC’ed regional data which we will use
as an input TAC to perform kinetic analysis.
In addition, we are also doing static SUVR analysis (sum of frames
from 60-90 mins) in which I am scaling input PET data with gray matter
cerebellum. In the output folder I see that upon scaling (when using
--save-input flag) we get a scaled input image which can be used as
SUVR. However, is this scaled image also PVC corrected or just scaled?
If not, then is it possible to get PVC’ed and scaled nifti image?
Thank you,
Sneha
