Contrast Considerations in Pregnancy

  • Henrik S. Thomsen


Radiological investigations using iodinated contrast media are not often carried out in pregnant patients in order to avoid exposing the foetus to ionising radiation [1]. Occasionally, however, investigations such as CT head scan or CT pulmonary angiogram may be necessary to protect the mother’s health, and the potential additional hazard posed by the contrast medium has to be considered. In addition, the fear of causing foetal harm or even death through medications used in pregnancy has meant that there has been no clinical research about the safety of drugs in pregnancy. Instead, medication safety information has only become available from case reports, epidemiological studies and animal studies, all of which have limitations that make determining the risks of using a particular drug during pregnancy difficult. For these reasons, the pharmaceutical industry discourages the use of medications during pregnancy and lactation: Likewise, the administration of contrast media is off-label, but not contraindicated, in this group of patients [2].
