Diagnostic test accuracy studies are performed in order to determine the value of a diagnostic test. Primary studies of diagnostic accuracy describe the accuracy of a test calculated using the number of true and false positive and negative cases of a given diagnosis of interest. Systematic reviews of diagnostic test accuracy are performed to identify accuracy of a test but also to investigate where the test might sit in a diagnostic pathway or determine how different tests compare against each other. This introductory discussion paper aims to give the reader an overview of the various features in primary and secondary diagnostic test accuracy study designs for medical imaging professionals.
诊断性测试准确性研究旨在确定诊断测试的价值。初步的诊断准确性研究描述了使用特定诊断的真阳性和假阳性及假阴性病例数计算得出的测试准确性。对诊断性测试准确性进行系统性综述，目的不仅在于确定测试的准确性，还要调查测试在诊断路径中的位置，或者确定不同测试之间的相互比较。本文旨在为医学影像专业人员提供初步和二次诊断性测试准确性研究设计的各种特点概述。
