magnetic resonance imaging (mri) is a diagnostic test that produces very clear images of the human body without the use of x-rays. an mri may be recommended if you are getting daily or almost daily headaches. an mri 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.
