Exposure to X-Rays and Nuclear Medicine Studies During Pregnancy


The inadvertent participation of an unborn child in a radiological study can be an emotional experience for both the mother and her physicians. The word "radiation" understandably invokes fear and uncertainty.

Such exposures must be prevented whenever possible. If they occur, they must be quantitatively evaluated and the risk put into perspective. Click on one of the links below for tabulations of fetal radiation dose consequential to common radiological procedures, and other information.

Sometimes fetal radiation exposure is necessary to protect the life or health of the mother. To quickly review some commonly encountered clinical scenarios, try the Risk Assessment Wizard.
