ID Number		2156
Study Type		In Vivo
Model		Static magnetic and RF (15 Mhz) exposure to pregnant mice (simulating MRI exposure) and analysis of developmental effects
Details		Pregnant Balb/c mice were exposed to static magnetic fields at 0.35 T as well as an RF field at 15 MHz at 61.2 milliwatts (simulating MRI exposure) for 16 hours on gestation day 8.75. The static magnetic field had a pulsed gradient of 2.3 X 10(-4) T/cm for 2.5 to 10 msec. The authors report no increase in placental resorptions, stillbirths, birth weight, or skeletal malformations with exposure. However, exposed pups did show a decreased overall crown-rump length (p < 0.001). With X-ray exposure as a positive control, both crown-rump length and fetal weight were significantly reduced and skeletal defects were increased.
