JKB, I've had a few MRI's, one "with contrast". They are a bit noisy, but if you stay up late beforehand, like TJ said, they're a bit hypnotic and you can get some solid sleep. Tech complained I was snoring louder than the machine! Also, like Sparky said, the contrast chemical makes you feel a bit warm, but not at all unpleasant, just different.

We'll be sending positive vibes and prayers...you'll do fine with it all!
