Intracranial meningiomas were detected in 164 of the 2,928 patients in the National Cancer Institute study of computed tomography (CT) in the diagnosis of intracranial tumors. The comparative effectiveness of contrast-enhanced and noncontrast CT scanning and other radiological modalities--plain skull radiography, angiography, radionuclide studies, and pneumoencephalography--was assessed. CT was demonstrated to be the most accurate method for detecting intracranial meningiomas (accuracy of 84.8% for noncontrast and 96.2% for contrast-enhanced CT). It was significantly more accurate than radionuclide studies and plain radiography, and was slightly more accurate than angiography. Pneumoencephalography was performed in only five cases, and identified a mass in four. Angiography was useful for increasing the percentage of specific diagnoses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
