about Invalid PTE with page-out ?

I just observe the Invalid PTE which is paged - out for studying.
In windbg, the command, !pte presents the the address, page-out with offset
of page file
however it doesn’t look like real offset, because when I monitor the page
file with filemon, the offset in windbg doesn’t appear.

how can I match with real offset in pagefile (such as pagefile.sys) and
PTE’s page file offset.
