Consult your physician. The following information should not replace the assessment and advice you have been receiving from your physician (cancer specialist, obstetrician, or any other healthcare provider). It is offered for your information only. The baseline risk in the general population for any type of fetal malformation/defect is about 1-3%. In general exposure to fetal radiation levels of less than 10 rads are not worrisome, and even at levels of 10-15 rads there maybe a slight increase in the baseline risk, which has yet to be proven. However at radiation levels of greater than 15 rads, the risk for major malformations increase by a factor of 2-3. The average dose to the fetus from a head CT scans is about 0.0005 rads which is an extremely negligible amount of exposure. Lead aprons are important safety measure that are effective at minimizing the amount of radiation that reaches the fetus, and are recommended for use in all radiation procedures by women of reproductive age, especially if in their 3-8 weeks of gestation which is a period of high vulnerability to the developing embryo.
