CT scan's are probably the least scariest of all of the scanning technologies. The machine has very open architecture (no claustrophobia issues) and it's fast. The contrast agent didn't bother me at all. Reactions to it are fairly rare.

I understand your fear. I never had a CT, MRI or PET scan before any of this also. Now I have had more of these scans over a three month period than most most people have their entire life.

It's not a sign of weakness to ask for anti-anxiety medications. Anxiety is normal. I took them for months and they really eased things a lot - so much so I slept through many of the scans. If you're not scared of the scanning procedure itself, then you're scared of the possible results.

I will keep you in my prayers for a great outcome.
