Back to the tube today.It's been nearly six months since I had a PET scan.  After the show today, it's time once again.  If you've never had a scan in a small tube, consider yourself very lucky.  Lots of us (including me) get very tense when we are in small areas and aren't allowed to move for many minutes...sometimes over an hour.  I haven't had any caffiene today, so that should help me relax.  I'll just be happy when  they slide me out of the tube and say "ok Scott, you're done!"  EXHALE.
