How is an MRI used to diagnose migraines and headaches?
This test produces very clear pictures, or images, of the brain without the use of X-rays. MRI uses a large magnet, radio frequency, and a computer to produce these images. An MRI may be recommended if you are getting daily or almost daily headaches. It may also be recommended if a CT scan does not show definitive results. In addition, an MRI scan is used to evaluate certain parts of the brain that are not as easily viewed with CT scans, such as the spine at the level of the neck and the back portion of the brain.
