Eventuella fosterskador till följd av magnetkameraundersökning på gravida kvinnor : En litteraturstudie med systematisk sökning

Sammanfattning: Background: During the recent years, magnetic resonance imaging (MRI) has evolved to become one of the most commend used diagnostic methods. Although MRI is considered safe and a good diagnostic method of foetuses and pregnant women, the research data is too small to claim that it is completely risk-free. Purpose: The purpose of this literature study was to identify possible risks of foetal defects in connection with MRI examination of pregnant women. Method: This essay is a quantitative systematic literature study where 13 articles were included after being searched in three different databases. Result: No significant differences in biological effects or hearing loss in foetuses exposed to MRI were detected. Heat increase could occur in connection with MRI examination and was influenced by the examination time and the field strength. However, the temperature generally stayed below the approved limit values. The using of gadolinium contrast agents could increase the risk of some foetal disease states as well as miscarriage and stillbirth. Conclusion: MRI could be a good alternative for anatomical imaging of pregnant women, although it should be used with great caution because of the limited research base. Thus, more research is needed in this area to determine the impact of MRI and gadolinium contrast agent on foetal development.
