What's the risk for fetus after i am doing x-ray and ct scan?

Unclear: There are multiple variables in determining the risk to fetus. The risk depends on the age of the fetus. The fetus is most suspective to damage in the first trimester. X-rays and ct exams taken far away from the wombs such as the head or extremities actually provide little to no radiation to the fetus. It is common procedure to cover the womb with lead if there is any chance of pregnancy.

Fetal age and dose: The 2 most important facts for determining risk are the age of the fetus at exposure and the quality and quantity of the radiation. A frontal chest or extremity x-ray would carry immeasurably low risk, while a multiphase ct scan of the abdomen and pelvis could carry significant risk. Please see your physician and if appropriate, request a dose estimate from a radiation safety officer.
