Neuro-imaging is generally not indicated for patients with TTH. Usually indicated when abnormal neurologic examination findings or atypical presentation or presentation not fulfilling the ICHD-3 criteria. Neuro-imaging with an magnetic resonance imaging (MRI) scan with and without contrast is preferred to non-contrast computed tomography (CT) scan. MRI is usually indicated to rule out underlying structural brain lesion or to evaluate brain and pituitary gland in patient presenting with typical features or highly suspicious of TTH.
