Re: CT scan or MRI and what is the difference?
I think it's worth it to have the MRI. I had a CT scan recently which clearly showed stenosis but the MRI I had a few days ago also showed (so clearly) a reherniation--it's just a much clearer picture where you can see, in my case anyway, the disc impinging the nerve root. On the other hand, many neurologists were trained before MRI's became available and can see what they need to with a CT scan. But if you can afford it an MRI will give you the most information. Good Luck.
