Pregnant magnetic resonance imaging (MRI) Technologist

There is no evidence in the scientific literature that a standard diagnostic MRI performed on a person who is pregnant will cause fetal biological effects. The literature suggests that the strength of the magnetic resonance (MR) field at diagnostic levels does not affect DNA synthesis, cell cycle, or proliferation kinetics in a fetus. The Food and Drug Administration (FDA) and other regulatory agencies have strict limits on MRI field strengths at diagnostic levels.
