Clinical safety of 3-T brain magnetic resonance imaging in newborns
The effects and potential hazards of brain magnetic resonance imaging (MRI) at 3 T in newborns are debated.
Assess the impact of 3-T MRI in newborns on body temperature and physiological parameters.
Material and methods
Forty-nine newborns, born preterm and at term, underwent 3-T brain MRI at term-corrected age. Rectal and skin temperature, oxygen saturation and heart rate were recorded before, during and after the scan.
A statistically significant increase in skin temperature of 0.6 °C was observed at the end of the MRI scan (P<0.01). There was no significant changes in rectal temperature, heart rate or oxygen saturation.
Core temperature, heart rate and oxygen saturation in newborns were not affected by 3-T brain MR scanning.
