One PET scan, coming up

I'm scheduled for a PET scan on July 25th. Should have results early the following week. Nervous time. No barium this time - yeah! Just a quick CT scan for contrast then on to the PET scan. If you've never had to drink barium then lucky you. It actually doesn't taste that bad - honestly, it really doesn't taste at all. It's just chalky and... Viscous. Big ick! Other than being injected with radioactive glucose, the PET scan isn't all that awful. Well, if you can lie absolutely and completely still for 45 minutes. My understanding is that if this scan is clean then I start on the rituxan maintenance schedule. If the scan is less than perfect I get four more rituxan treatments then see what's going on before moving forward. BTW, all of the spring babies have arrived and they are beauties.
