Computer tomography for diagnosis of intracranial tumours compared with other neuroradiologic procedures

The diagnostic effectiveness of computer tomography has been assessed in a series of 361 patients with the primary clinical problem of a possible intracranial neoplasm. Of these patients, 171 were shown to have a tumour, confirmed at microscopy in 115 instances. Computer tomography was compared with other established neuroradiologic procedures, such as encephalography, angiography and isotope scanning, all of which were frequently used in this series of patients.
