I had a PET scan May 19, 2009 at Tristian Associates. On May 21st Dr. Shah called me with the results.  I do not have Alzheimer's! What I have is an abnomailty in the memory area of the frontal lobe that needs to be treated the same way. May 21st has just become the 2nd time I have been born again! What they ended up doing was to confirm that I have the "Crude" and asked me to congratulate my Harrisburg team for doing such a great job on the diagnosis.
