Had mri for headaches. with & without contrast. normal. would mri also show anything else. such as multiple sclerosis?

Normal: If "normal" then you do not have multiple sclerosis. You may have migraines. I see numerous migraine patients with normal MRI studies. Best course of action is to talk to the doctor that ordered the MRI and talk over a plan.

If disease present: MRI should reassure you, as lesions characteristic of MS are not noted and there is no sign of bleeding or MS.
