Computed tomography in neurosurgical practice

CT diagnosis of intracranial diseases such as tumors, vascular disorder, trauma, infectious diseases, and congenital malformations which were clinically important diseases in neurosurgery was stated briefly. CT was the most suitable not only for the diagnosis of these diseases but also for follow-up of effects of neurosurgery and radiotherapy or chemotherapy, and for discovery of various complications and sequelae. Moreover, CT are applied to establishment of radiation fields and radiation doses for radiotherapy and to biopsy and paracentesis drainage of cysts under CT control. The usefulness of CT for diagnosis of diseases of spinal cord, spine and spinal canal have been already established. The usefulness of CT for neurosurgery including dynamic and functional analysis by the development of apparatuses is expected. (Tsunoda, M.)
