Glad you made it through the tests intact, even if it was a rough go.
Something that I've learned to do and is very helpful: Visualization. It's basically an exercise in escape, imagining a different reality or an invisible process. When I'm going through an uncomfortably long PET or MRI, I close my eyes and relax, then see myself sitting with a group of like minded friends and cohorts discussing whatever suits my fancy.
Sometimes they are all at the test with me and hold my hand, or do Reiki, or massage. Anything can happen in your imagination!
Same with radiation. I close my eyes and "see" my vertebra, then I "see" the radiation melting the tumor mass away.
I had to practice every day to learn to relax. Meditation MP3s helped...self hypnosis. Took 20 minutes a day and devoted it to relaxation and inducing a state to visualize. Now I can do it almost on the second for any uncomfortable or fear inciting procedure.
My oncologist also lets me use CAM, herbs, etc. as long as I talk to him about it beforehand so he can advise of any conflicts or dangers.
I use a standardized valerian root capsule and chamomile tea 30-60 minutes prior to a procedure. If it's fasting, they usually allow taking medication with a very small amount of water. I always check first.
I'm still wincing, however, with needle sticks. Used to be they never bothered me, but in the last year, I've developed a real aversion to them, and now, even a 24 ga. butterfly needle makes me cringe! I'm not so tough after all, but it's OK. I'm allowed.
Keep the faith. You will never be given more to bear than the grace given you to bear it.
