Grannyrebel I had one last year and was on here asking the same question as you! It's totally bearable, you are in the scan only up to chest level, it's light inside and you can also see at the end of the tube. There's easy listening music even if there are short burst of noise. I also had contrast which I was dreading, in fact it's just an injection given towards the end, just felt slightly flushed for a couple of minutes and that was it. Soon after they come in and tell you it's all done. It took about half an hour. You have a panic button in your hand the whole time. The anticipation was much worse! Good luck!
