I went for an MRI this week and the neurosurgeon estimates I have 20% diameter of my spinal cord at the injury site. Anybody else out there that has had an MRI post injury? I am wondering if there is anyone out there that has seen any changes in the spinal cord over time. The Dr. indicated to me that the tissue I was seeing surrounding the remaining cord at the site of injury was the result of tissue necrosis but I am wondering what it is exactly. Is it 'scar tissue' or is it 'dead tissue' or possible surrounding tissue which is swollen?
