Abstract
Specialized and up-to-date knowledge is required to identify and manage the risks associated with advanced biomedical research. Additional complexities need to be considered when the research involves infants or young children. In this article, we focus on recent information about the physical risks of pediatric magnetic resonance imaging research and highlight information gaps. With an eye to assisting institutional review boards and researchers, we consider strategies for the management of these risks and formulate key questions aimed at exposing hidden hazards. Institutional review boards should ask these questions, and researchers should bear them in mind as they develop research protocols.

Notes
1While issues associated with the disclosure of risks to participants lie beyond the scope of this article, which focuses on risk identification and management, the questions listed at the end of each section could be used to guide the informed consent process between researchers and participants or their surrogate decision-makers.
2A search of ClinicalTrials.gov, using the search terms “neonate” and “MRI,” revealed 31 registered trials that are currently recruiting healthy and sick neonates (http://clinicaltrials. gov/ct2/search. Accessed April 8, 2009.)
3Many of these concerns apply also to critically ill older children who are patients in intensive care units.
4An MRI compatible device neither poses a physical hazard nor malfunctions in the MRI scanner.
5This study was conducted with involvement by manufacturers of the contrast agent.
