Hi. Really not sure what to recommend. For one thing though I was always taught that an MRI is better then a CT scan. Gives better details when trying to determine what is wrong. Right or wrong I don't know but that is always what I was taught.

You asked whether you should have a Cervical MRI, Ct scan or brachial Plexus MRI. Didn't you state that you already had a cervical MRI plus other tests like EMG NCV tests that were normal?

I am not familiar with a brachial plexus MRI so cant comment on it. I guess that would be the next logical test if you've had the other tests done and they were normal.

What did cross my mine and you didn't state it in your post but what type of doctor are seeing for a diagnosis? Getting to the right specialist is extremely important. And at least in my opinion if you are near a major teaching hospital I would suggest going that route.

Hope you get the answers that you are looking for ...
