Contrast a concern: The MRI should not affect a pregnancy. In fact, MRI is used to image fetuses. However, breast MRI uses contrast to best detect abnormalities, and MRI contrast's effects in pregnancy are not fully understood and because it has not been proven safe, most imaging centers do not use contrast in pregnant women, to be as safe as possible. Consider a pregnancy test and talk with your doctor.

Probably safe: There are safety concerns about the effects of both the MRI (heat and noise) and of the contrast on the fetus although probably safe. Also, the test may be useless because even large tumors may be missed on an MRI obtained during pregnancy because of the changes taking place to allow milk production .Better to have a pregnancy test and be sure it is negative before a screening breast mri.
