技术的发展和医学图像中生物特征定量测量的更加严格,引起了人们对使用定量成像生物标志物(QIB)来测量这些特征的变化的兴趣日益浓厚。 QIB 在临床前或临床环境中的性能至关重要的是三个主要计量领域:测量线性和偏差、重复性以及在条件变化时一致重现等效结果的能力,正如任何临床试验所期望的那样。不幸的是,迄今为止的性能研究在用于评估临床使用 QIB 的设计、分析方法和指标方面存在很大差异。因此,很难或不可能整合不同研究的结果或使用报告的结果来设计研究。北美放射学会 (RSNA) 和定量成像生物标志物联盟 (QIBA) 与技术、放射学和统计专家一起开发了一套技术性能分析方法、指标和研究设计,提供与广泛接受的计量标准一致的术语、指标和方法。本文件为 QIB 绩效研究的进行和评估提供了一致的框架,以便可以比较、对比或组合多项研究的结果。
Technological developments and greater rigor in the quantitative measurement of biological features in medical images have given rise to an increased interest in using quantitative imaging biomarkers (QIBs) to measure changes in these features. Critical to the performance of a QIB in preclinical or clinical settings are three primary metrology areas of interest: measurement linearity and bias, repeatability, and the ability to consistently reproduce equivalent results when conditions change, as would be expected in any clinical trial. Unfortunately, performance studies to date differ greatly in designs, analysis method and metrics used to assess a QIB for clinical use. It is therefore, difficult or not possible to integrate results from different studies or to use reported results to design studies. The Radiological Society of North America (RSNA) and the Quantitative Imaging Biomarker Alliance (QIBA) with technical, radiological and statistical experts developed a set of technical performance analysis methods, metrics and study designs that provide terminology, metrics and methods consistent with widely accepted metrological standards. This document provides a consistent framework for the conduct and evaluation of QIB performance studies so that results from multiple studies can be compared, contrasted or combined.
