The impact of computed tomography on neuroradiologic practice

To assess the impact of computed tomography (CT) of the head on neuroradiologic and diagnostic practice, we analyzed its capabilities, performance, and usage in our practice during the past 18 months. The results were compared to similar data on other neurodiagnostic tests, i.e., electroencephalography (EEG), A-mode echoencephalography, cerebral angiography, cerebral pneumography, and nuclide brain scanning. All diagnostic techniques except EEG were used less often as the capabilities of CT became known to our clinicians.
