Ethical Discussion of Incidental Findings in Neuroimaging Studies

During neuroimaging research, if the incidental findings can bring significant medical benefits to the research participants and their informed consent has been obtained, researchers should inform them of the incidental findings. This obligation can be ethically justified through the principles of reciprocity, altruism, and the easy rescue theory. In addition, the easy rescue theory suggests that researchers bear a moral responsibility to make reasonable efforts to identify incidental findings, while balancing the cost and benefit of the research protocol. This paper also proposes the classification of incidental findings and specific feedback plans to ensure that research participants receive timely information about discoveries that may significantly impact their health. However, defining the scope of incidental findings is quite challenging and requires a comprehensive consideration of factors such as the scientific validity, clinical significance, and practical feasibility.
