I'm not sure what you mean. If you are turning off PVC, why are you computing RBV and MGX? What is your command line? What do you mean that these options don't seem to work?

Hi Douglas,

Thanks for helping.

To have an only rescaled voxel-wise PET image, these options seem to work only when -rbv method is used and not -mgx.

Do you know why ?

Best,

Matthieu

You will need to set --psf 0 and --no-tfe to fully turn off PVC.

Dear Douglas,

Is it possible to use mri_gtmpvc command in order to intensity normalize PET images without applying PVE correction by setting --psf to 0 ?

Best,

Matthieu
