Would an MRI scan of the brain without contrast definitely show a tumor (or any other brain condition)?
Its possible that a MRI with contrast would find something missed on a routine MRI. The problem is that there are different contrast agents for different circumstance and there is no way to know which agent is the best one to use without knowing what type of problem to look for. Consequently, a contrast MRI may offer just a slight advantage, but even a slight increase in resolution could be helpful. If the drugs you are taking aren’t working, let your doc know. There is no point in taking drugs that don’t work and there are many alternative drugs and treatment approaches (for migraines) that might be worth trying. You would have to taper off the Nortriptyline to do it safely. Do you live next to a golf course or in an area where there might be a lot of pesticide use?
