诊断准确性的衡量标准，如敏感度、特异度、预测值和接收器工作特性曲线，往往看起来像是抽象的数学概念，与临床决策或临床研究几乎没有关系。这篇文章的目的是提供这些概念的定义和例子，说明它们在特定的临床决策任务中的有效性。特别是，提供了九个原则来指导这些概念在日常放射学实践中的使用，在解释临床文献和设计临床研究中。了解这些原则及其适用的诊断准确度的衡量标准，对于正确评估和使用诊断影像检查至关重要。(C)RSNA，2003年。
Measures of diagnostic accuracy, such as sensitivity, specificity, predictive values, and receiver operating characteristic curves, can often seem like abstract mathematic concepts that have a minimal relationship with clinical decision making or clinical research. The purpose of this article is to provide definitions and examples of these concepts that illustrate their usefulness in specific clinical decision-making tasks. In particular, nine principles are provided to guide the use of these concepts in daily radiology practice, in interpreting clinical literature, and in designing clinical research studies. An understanding of these principles and of the measures of diagnostic accuracy to which they apply is vital to the appropriate evaluation and use of diagnostic imaging examinations. (C) RSNA, 2003.
