Is intravascular iodinated contrast material contraindicated for use in pregnant women?
No. Even though iodinated contrast material crosses the blood-placental barrier and enters the fetus, there have been no reports of neonatal hypothyroidism or teratogenic effects following maternal intravascular administration of iodinated contrast material.
Because there are no available data to suggest any potential harm to the fetus from exposure to intravascular iodinated contrast administration, iodinated contrast material can be administered to pregnant or potentially pregnant patients when needed for diagnostic purposes. A more important consideration in pregnancy is the risk of radiation exposure to the fetus from imaging studies.
