This question is difficult to answer with a simple "yes" or "no." MRI (magnetic resonance imaging) is considered a safe exam. However, conclusive information showing how safe MRI is for pregnant women and the fetus is not yet available. MR imaging is generally not performed on women in the first twelve weeks of pregnancy (first trimester).
Physicians typically do not perform MRI on pregnant women unless there are strong medical indications. Depending on the condition, there may be other exams available, such as ultrasound, to help diagnose a medical condition.
If there is a strong medical reason for an MRI, your physician may consult with a radiologist to determine if MRI is the best course of action before proceeding. An abbreviated MRI exam may be performed, to reduce the time in the magnetic field, based on the recommendation of the referring physician and radiologist. Please consult with your physician for more specific information.
