As defined by the Cochrane Collaboration, a systematic review is a review of evidence with a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant primary research, and to extract and analyze data from the studies that are included in the review. Meta-analysis is a statistical method to combine the results from primary studies that accounts for sample size and variability to provide a summary measure of the studied outcome. Systematic reviews of diagnostic test accuracy present unique methodological and reporting challenges not present in systematic reviews of interventions. This review provides guidance and further resources highlighting current best practices in methodology and reporting of systematic reviews of diagnostic test accuracy, with a specific focus on challenges and opportunities for MRI imaging.

根据 Cochrane 协作组织的定义，系统评价是对证据的评价，其具有明确提出的问题，使用系统和明确的方法来识别、选择和批判性评估相关的原始研究，并从纳入评价的研究中提取和分析数据。荟萃分析是一种统计方法，用于组合来自原始研究的结果，考虑样本量和变异性，以提供研究结果的综合衡量指标。诊断性试验准确性的系统评价提出了独特的方法学和报告挑战，这些挑战在干预措施的系统评价中并不存在。本综述提供了指导和进一步的资源，强调了诊断性试验准确性的系统评价的当前最佳方法学和报告实践，特别关注 MRI 成像的挑战和机遇。证据水平：2 技术效果：2 级 J.
