Neuroradiology and headaches

Headache is one of the most common outpatient pain conditions encountered in both physician offices and emergency departments. Establishment of an accurate diagnosis, accomplished only by athorough history followed by a physical examination, is critical before treatment can be initiated. Many patients undergo evaluation with computed tomography and more recently magnetic resonance imaging to exclude important abnormalities. It is known that a little percentage of patients showed significant neuroradiologiacal abnormalities and the rate of significant intracranial abnormalities inpatients with headache and normal neurological examination exists.
