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.
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.
关于3T磁共振成像（MRI）对新生儿的影响及潜在危害存在争议。
评估3T MRI对新生儿体温和生理参数的影响。
49例早产和足月出生的新生儿在矫正胎龄时接受了3T脑部MRI检查。在扫描前、扫描期间和扫描后记录直肠温度、皮肤温度、血氧饱和度和心率。
MRI扫描结束时，皮肤温度有统计学意义地升高了0.6°C（P<0.01）。直肠温度、心率或血氧饱和度无显著变化。
3T脑部MR扫描未影响新生儿的核心体温、心率和血氧饱和度。
