描述了在诊断成像中用于表达观察者关于分类数据的一致性的统计测量。这些措施被用来表征成像方法的可靠性和疾病分类的再现性，偶尔非常小心，作为准确性的替代品。该评论集中在机会校正指数，卡帕和加权卡帕。影像学文献中的例子说明了计算方法以及疾病患病率和评级类别数量的影响。其他措施的协议，使用频率较低，包括多个评级Kappa，引用和简要描述。(C)RSNA 2003年。
Statistical measures are described that are used in diagnostic imaging for expressing observer agreement in regard to categorical data. The measures are used to characterize the reliability of imaging methods and the reproducibility of disease classifications and, occasionally with great care, as the surrogate for accuracy. The review concentrates on the chance-corrected indices, kappa and weighted kappa. Examples from the imaging literature illustrate the method of calculation and the effects of both disease prevalence and the number of rating categorie. Other measures of agreement that are used less frequently, including multiple-rater kappa, are referenced and described briefly. (C) RSNA 2003.
