99mTc-pertechnetate thyroid scintigraphy was performed on 67 patients with a pinhole camera and a rectilinear scanner. The dual set of images was interpreted blindly by four nuclear medicine physicians. Observer performance with each of the two imaging techniques was evaluated by the receiver operating characteristic (ROC) method and by multivariate information analysis (MIA). Performance was superior for the four observers when interpreting the pinhole images, identification accuracy ranging from 70 to 94% with the pinhole images and only 49 to 63% with the rectilinear scanner.
对67例患者使用针孔相机和直线扫描仪进行了99m锝-高锝酸盐甲状腺闪烁扫描。由四名核医学医师对这两组图像进行盲法解读。通过受试者操作特征（ROC）方法和多变量信息分析（MIA）评估了两种成像技术中每种技术的观察者表现。在解读针孔图像时，四名观察者的表现更佳，针孔图像的识别准确率为70%至94%，而直线扫描仪的识别准确率仅为49%至63%。
