Unfortunately I don’t have FacebookYou might like to post that MRI image on Jen Brea's Facebook group for CCI, and see what people there think.
It was a brain MRIThe resolution of the image looks a bit poor, which may make it hard to measure things. Was that a brain or cervical MRI? Doctors who are experts in diagnosing CCI typically want a cervical T2 weighted MRI image like the one I did below. If they gave you a DVD you can usually select different slices from the three planes.
Hopefully you get a reply from the doctor, but to my layman's eyes it would seem very difficult to diagnose or exclude CCI based on the attached image.
