Overview
There are no known safety hazards associated with the performance of an MRI, especially after the first trimester.[1] However, data evaluating the safety of MRI during pregnancy is limited and an MRI is indicated only when other imaging modalities such chest x-ray and echocardiography are inconclusive or to identify aortic diseases in pregnancy.[2] Currently, the FDA recommends prudent use of MRI during pregnancy.
Contrast MRI using gadolinium is contraindicated as gadolinium crosses the trans-placental membrane and exposes the fetus to teratogenicity.
