Comparison of the accuracy of brain scanning and other procedures used for brain tumor detection

Abstract
Data indicate that the brain scan has a high degree of accuracy in localizing intracranial tumors. The combination of brain scanning, electroen-cephalography, and skull films failed to show an abnormality in only 5% of 44 proved brain tumors. This degree of accuracy is the same as that of combined angiography and air encephalography. The data support the position that brain scanning is capable of detecting brain tumors and should be used as a routine screening procedure. It is not felt that the minor procedures obviate the necessity of doing a major procedure, since the major procedures offer additional information. However, enough data has accumulated to allow one to rely upon brain scanning and the other atraumatic diagnostic procedures to exclude a central nervous system mass lesion, except when the clinical syndrome obviously calls for angiography or pneumography.
