MRI scans today - brain and knee

weird thing - I was so so nervous - BUT it was OK, very noisy but I chose - yes chose Eva Cassidy CD and had knee MRI first - so i was outside the machine. Fell asleep a couple of times and woke up with a bit of a jump - even though the machine is noisy - then had the brain scan (for my optic nerve) and even though I was then inside the machine it was again OK...............lovely radiographers/radiologists - very professional. I hope they don't find anything wrong, espescially with the brain one ! The knee is playing up again - constantly gnawing at me that I call it 'Gnawreen;. Fingers crossed eh.
