title: [Indication and efficiency of CT in neurosurgery].
abstract: Computed tomography (CT) is one of the greatest diagnostic advancements for neurosurgery. Except for angiography, the usual contrast examinations have become unnecessary. Site, extent and topography of hypodense and hyperdense lesions correlate partially with the neuropathological findings. The diagnostic value is increased by measuring the grade of density, highlight spectra, and the intravenous and intrathecal contrast injection as well as modern reconstructions. Even the smallest lesions can be found. The most important advancements in recent years are the diagnosis of blood-brain barrier disturbances and lesions of the brain stem and spinal cord.
