7T MRI in infants could improve cerebral diagnostic quality, but safety should be evaluated before standard use. In this study, twenty infants without respiratory support between term-equivalent age and 3 months corrected age, were scanned on 7T directly after 3T MRI. Vital signs (heart rate, oxygen saturation and respiratory rate), temperature (rectal, body and brain), COMFORT scale scores and adverse events were monitored throughout the process. None of these parameters changed around 7T MRI. Also, heart rate and temperature were not significantly different during 7T, when compared to 3T MRI. Therefore scanning infants at 7T appears to be safe.
