Works in PET activation study

[Tetsuji Rai]

Hi, all,
   I'm working on PET activation study in Japan.   But we don't know 
current status what and how major groups (St. Louis group, Hammersmith 
group, etc.) are doing, because the only source is papers.
I'd like to know about it.   Does anyone know there is any networks
on that or how to reach them on Internet (email address is also ok) ?
I know a bit, but want to know more.
  Any help I can get would be appreciated.   Please send email for
quick response.

Regards

-Tetsuji
