@rllampton By now you have already had your PET scan. I am just shy of 3mo out from my chemo radiation at Mayo and scheduled for my first PET scan / NavDX on March 24th. I am, like many others, nervous about recurrence. In regards to anxiety with going in to the scan, Ativan is something I took 30min prior to my radiation treatments x 2 / day in December. I'm not claustrophobic but when my face was compressed under the mask plus mouth guard, I experienced anxiety in a very new way. The Ativan plus mental imagery and breathing helped center me for all 20 treatments. Good luck and let us know how you're doing.
