Brain scanning with the Anger multiplane tomographic scanner as a second examination evaluation by the ROC method.
AI Summary
Key Findings
Abstract
One hundred and one patients (43 abnormal, 58 normal) were re-examined with a commercial prototype of the Anger multiplane tomographic scanner after brain scintigraphy. The studies were interpreted independently by four observers of varying experience. Observer performance, in terms of ROC curves, was substantially better when interpreting the tomographic brain scans and camera scintigrams together or the tomographic scans alone than when interpreting the camera images alone. Re-examination with the scanner increases the accuracy of brain scintigraphy (observer performance) in cases in which there is difficulty distinguishing intracranial lesions from superficial foci of activity by camera scintigraphy alone.
