ps it didn't hurt in any way either!
we are very concerned as the last time he had an mri with contrast he had a very severe anaphylactic shock
For my Petscan which was in the afternoon, I had to starve since the night before (made me a little lightheaded) "they" also insist you have someone else to drive to and from the hospital -more for car insurance I think, but glad someone came with me!
When I got there -as with the normal scans, I had to remove all metal things -earings,rings etc and remove my denture plate. They took me into a very quiet cubicle with no windows.(the whole unit is soundproofed) and gave me an injection of relaxant..male nurse was very calm,kind and quiet and explain what would happen after a rest. Then I had to "rest" in this darkened room and he explained there would be "tranquil" muszak and I could have an eye cover if I wanted..the idea is to deep relax you...I went to sleep!
About 15 minutes later he quietly arrived dressed like a spaceman!! pushing a large cube that was covered with radioactive symbols. After checking I was OK, he then connected me to the cube and I was injected with a measured dose of something radioactive...I did not glow!
Then after putting all the space stuff away, he wheeled me into the scanner room..like an ordinary scanner but longer. Then I was strapped down tightly,once I was comfortable, with three big straps. (you must not be able to move even a fraction)
then it was explained that the scan would take about 90 minutes and they left the room, although they could see me through the glass partition and were in contact verbally -they asking if I was OK.
once again. muszak, while the machine VERY slowly inched along...I fell asleep once again.
At the end I was taken back to the cubicle and given LOTS to drink and shown where the loo was!!
Apparently all the quietness is to slow down your brainwaves and organs so that the long scan can take in everything "at rest"..certainly worked with me!
The results go straight to the specialist although they did say they could not see anything untowards. Biggest shock was to receive the CPAM sheet months later to see it cost 1,000 euros!! thank god it was free!
hope this reassures you somewhat, but please come back if you want to ask some more. good luck!
