Question about pvcorr

[juliapottkaemper]

Hi,
I had a question about the pvcorr option. The output you get is a perfusion image corrected for either WM or GM. How and (more importantly) when is the perfusion image smoothed (as the standard setting: spatial regularisation)? And how exactly is the correction for both tissue types done? Is this correction performed before or after the perfusion image was smoothed? Thanks in advance!

The outputs are separate estimates for GM and WM perfusion. This is done using the estimate of GM and WM partial volume in each voxel, spatial smoothing is done as an integrated part of the process.
