Markus,

"The reason why the field was widened was because the guy who put in the peg saw a bigger area" - does that mean he looked at your CT or PET, and thought the treatment area was too narrow?

Exposure to mice? Wow. As in, consistent caregiver, or occassional exposure? Stupid question, but was it mice in particular, or any rodents? My son and his girlfriend had a gerbil "village", and I did play with the critters a few times. Did your MO bring up the mice issue, or was it good research on your end (OK, MD for a wife would be very handy, I'd think).
