What an interesting discussion !!
When I had a pet/ct scan the technicians allowed me to use the public restrooms whenever I wanted. However they took me to a small room for about an hour and half after the injection and before the scan. They asked me not to move around, talk, read, eat, do needlework or any other activity. I was allowed to drink water though. I use prescription eye drops, so when it was time to use the drops the technicians came into the room and put the drops in my eyes and wiped the excess drops in the area around my eyes for me.
A technician took me out to the front lobby of the hospital for me to meet my ride after the scan. She asked me to stay away from pregnant women for 24 hours. I guess she wasn't thinking. All kinds of people including pregnant women walk around hospital lobbies.
The technicians told me moving around too much after the injection and before the scan allows the radioactive contrast to get stuck in the muscles and they don't get accurate results.
The injection for bone scans is radioactive too, but the guidelines are not nearly as strict. However once after a bone scan injection the technician thought he gave me too much and came running out to the waiting room to find me. He told me he had to check my radiation levels, because he tought he gave me too much. You should have seen all the other people in the small waiting room scatter !!!!!!!!!! The waiting room quickly turned into a private waiting room just for me. I was okay and the levels were within the proper range.
