[Imaging for disorders in neurology and neurosurgery]

Imaging has become increasingly important for diagnosis and treatment of disorders in neurology and neurosurgery. Often, however, physicians are uncertain which imaging modality to chose for diagnosis and which techniques can be used to help for treatment. To answer a specific question clinicians have to rely on history and clinical findings. According to a cardinal clinical symptom or sign the imaging technique with the highest sensitivity and specificity for the given problem is chosen. In this review imaging techniques for the most common cardinal symptoms and signs in neurology and neurosurgery which need imaging for management are discussed.
