While conducting research, it is crucial to protect our participants from undue risk. For human neuroimaging, many institutions require excluding pregnant people from completing magnetic resonance imaging (MRI) for research to minimize potential risk. This often entails mandatory urine pregnancy testing for all people assigned female at birth who have started to menstruate. This restriction stemmed from early concerns about fetal health from animal studies that have not been substantiated through human research. Yet, some institutions do not require this and many researchers are actively pursuing human fetal MRI.Animal studies conducted in the 1980–90s raised concerns that MRI during pregnancy might confer negative effects on offspring (1-5), with acoustic noise and tissue heat absorption being typical mechanisms of concern–rather than radiation or radioactive tracers with X-ray, CT, or PET. However, several animal studies employed long-duration scanning (eg, 4 or 8 hours) not realistic or typical for human neuroimaging studies, eg,~ 30-90-minute head MRI. Furthermore, environmental noise is damped in utero and the specific absorption rate (SAR) is tightly limited under normal scanning parameters to avoid heating (6).
