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.
101名患者（43名异常，58名正常）在脑闪烁扫描术后，使用Anger多平面断层扫描仪的商用原型进行了复查。由四名经验各异的观察者独立解读这些研究结果。就ROC曲线而言，当同时解读断层脑扫描和相机闪烁图或仅解读断层扫描时，观察者的表现要比仅解读相机图像时好得多。在仅通过相机闪烁图难以区分颅内病变与浅表活动灶的情况下，使用扫描仪进行复查可提高脑闪烁扫描（观察者表现）的准确性。
