Value of Patient-Directed Brain Magnetic Resonance Imaging Scan with a Diagnosis of Migraine

Brain MRI obtained at the specific request of patients with a diagnosis of migraine in the presence of normal neurologic examination results has a yield that is equivalent to that of the general asymptomatic population. Patients do not seem to have more insight than the examining clinician with regard to detecting underlying structural abnormalities, and brain MRI should not performed as part of the routine evaluation of migraine without a clear clinical indication.
