title: [Diagnostic imaging of headache].
abstract: The diagnosis of headache is based on the subjective symptom, and it is generally classified into the primary headaches, which have intracranially no abnormality, and the secondary headaches, which have organic abnormality. Neuroimaging examinations, computed tomography (CT) scan, and magnetic resonance imaging (MRI) are useful for differential diagnosis and can perform to rule out vascular malformation, brain tumor, and other pathologies, and to confirm the diagnosis. There are cases of the secondary headaches resembling the primary headaches and patients complaint of pain by complex of them, in those cases, it is necessary to perform more detailed neuroimaging(three dimensional MRA, helical CT and so on). These neuroimaging could contribute to make diagnosis and treatments for the patients.
