MRI is used routinely in research with children to generate new knowledge about brain development. The detection of unexpected brain abnormalities (incidental findings; IFs) in these studies presents unique challenges. While key issues surrounding incidence and significance, duty of care, and burden of disclosure have been addressed substantially for adults, less empirical data and normative analyses exist for minors who participate in minimal risk research. To identify ethical concerns and fill existing gaps, we conducted a comprehensive review of papers that focused explicitly on the discovery of IFs in minors. The discourse in the 21 papers retrieved for this analysis amply covered practical issues such as informed consent and screening, difficulties in ascertaining clinical significance, the economic costs and burden of responsibility on researchers, and risks (physical or psychological). However, we found little discussion about the involvement of minors in decisions about disclosure of IFs in the brain, especially for IFs of low clinical significance. In response, we propose a framework for managing IFs that integrates practical considerations with explicit appreciation of rights along the continuum of maturity. This capacity-adjusted framework emphasizes the importance of involving competent minors and respecting their right to make decisions about disclosure.
MRI 常用于儿童研究,以生成有关大脑发育的新知识。在这些研究中,检测到意外的大脑异常(偶然发现;IFs)会带来独特的挑战。虽然成年人的发病率和意义、护理责任和披露负担等关键问题已经得到了实质性的解决,但对于参与低风险研究的未成年人,相关的经验数据和规范分析较少。为了确定伦理关注点并填补现有空白,我们对专门关注未成年人 IF 发现的论文进行了全面审查。在这项分析中检索到的 21 篇论文的论述充分涵盖了实际问题,如知情同意和筛查、确定临床意义的困难、研究人员的经济成本和责任负担,以及风险(身体或心理)。然而,我们发现很少有关于未成年人参与关于大脑 IF 披露的决定的讨论,特别是对于临床意义较低的 IF。有鉴于此,我们提出了一个管理 IF 的框架,该框架将实际考虑因素与沿着成熟度连续体的明确权利意识相结合。这种能力调整框架强调了让有能力的未成年人参与并尊重他们做出披露决定的权利的重要性。
