Ethical Oversight and Social Licensing of Portable MRI Research.

This article explores two questions: (1) whether portable MRI research might escape regulatory oversight altogether under existing U.S. privacy and research ethical frameworks, leaving research participants without adequate protections, and (2) whether existing regulatory frameworks, when they do apply, can guard society's broader interest in ensuring that portable MRI research pursues socially beneficial, ethically sound aims that minimize the potential for externalities affecting nonparticipating individuals and groups, who might be stigmatized or otherwise harmed even if they decline participation in the research.
