What are the benefits of MRI for pregnant people?
An MRI is very good at imaging internal organs and other soft tissues. It can provide information that is important to know before your baby is born. Your doctor can explain what information he or she is looking for and why.
An MRI can also provide information about the developing fetus when ultrasound cannot.
What are the risks of MRI for pregnant people?
MRI is safe imaging for most people, including pregnant people. Risks typically depend on a person's specific medical condition. We will carefully review the risks and benefits with you.
Does an MRI use contrast?
Some MRI exams use IV (intravenous) contrast to help a radiologist with a diagnosis. Mass General does not routinely use contrast in patients who are pregnant because research is limited about the risk to a fetus. The exception is when the patient, the ordering doctor and the radiologist decide together that the benefit of using contrast outweighs the risk.
Does an MRI use radiation?
Unlike X-rays or CT exams, an MRI does not use radiation. It uses a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body.
