Jim - Thank you for your update on the pig-cell transplant. You are a brave pioneer and I'm glad to hear you are feeling better and hope you see continued improvement.! Sorry to hear that the PET scan is such a pain though. I'm curious about it. Jim Finn wrote: The second dreaded PET-scan (see previous reports) has not been performed. They are having serious problems with the machine. And that's fine with me! It has been re-scheduled (again) for the middle of August. Although I have agreed to having it (and I will), that doesn't make it pleasant. What actually happens during a PET scan? I always pictured it as a rather benign experience like the MRI. Joan 56/8
