Can someone tell me if they know about a radiology forum where you can ask questions about scans and have them be answered by physicians?

Specifically, I would like to know about a recent MRI scan that showed I have atrophy in the medulla and thinning in the spinal cord above my spinal cord injury. I was told by my neurologist that it is normal to have that above the injury site of spinal cord injured people. I would like to confirm that it is normal.

Thanks!
