Hi, I Have Klippel Feil Syndrome, Spina Bifida, Retroflexed Odontoid,

Hi, I have Klippel Feil Syndrome, Spina Bifida, Retroflexed Odontoid, Cervikal Spinal Stenosis, Scoliosis, Osteopenia. My last MRI scan shows a shadow between C1 and C2. They tell me it is nothing. I am concerned because the MRI was done without contrast. Don't you think It should be more tested???
