Headache may be caused by primary disorders, such as migraines, or secondary disorders, such as intracranial neoplasm or hemorrhage. Imaging plays an important role in differentiating between primary and secondary headache disorders. This article reviews the effectiveness of computed tomography (CT) and magnetic resonance imaging (MRI) in the evaluation of a patient with a headache. It also discusses the utility and cost-effectiveness of performing imaging studies in patients with a headache and a normal neurological exam. Emerging imaging techniques such as functional MRI, positron emission tomography (PET) scans, and voxel-based morphometry (VBM) are also discussed.
头痛可能由原发性疾病引起，如偏头痛，或继发性疾病引起，如颅内肿瘤或出血。影像学检查在区分原发性和继发性头痛疾病方面起着重要作用。本文综述了计算机断层扫描（CT）和磁共振成像（MRI）在评估头痛患者中的有效性。它还讨论了对头痛且神经系统检查正常的患者进行影像学检查的实用性和成本效益。还讨论了诸如功能磁共振成像、正电子发射断层扫描（PET）和基于体素的形态测量学（VBM）等新兴影像学技术。
