I have a question for Dr. Heinrik. I would like to know if a pancoast tumor would show up on a cervicle spine mri? As you may have read in past post, that is my greatest fear. I had a clean ct scan in feb and started having "symptoms" in May. I was just wondering if I can absolutely eliminate that from my thought process, with a clean cervicle mri. I understand that nothing is absolute, but is it enough to put my mind at ease? Or should I fight for more test? I have a copy of the film on cd. My neurologist gave it to me. He didn't see anything and neither do i, but I'm soooo scared. Please respond...
