Hi...
I have had countless CAT scans, MRIs and PET scans.
Three bouts of cancer will give you more contact with every facet of the medical field than you will ever want.
I have to be sedated for MRIs...I had no idea I was claustrophobic until I was put in an MRI tube. Total freak out time. I tell them that I will need to be sedated every time they schedule an MRI. They didn't authorize the sedation drug one time and they couldn't get me in the tube. They weren't very happy but they had to reschedule the MRI.
PET scans I can handle but it's not a good time. I need the tech to talk to me pretty much every couple of minutes or I get VERY anxious.
CAT scans are a piece of cake.
