[|Human|] My wife is 7 weeks pregnant and possibly has a blood clot in the lung.  The doctor we saw in emerge said she should go for a ct scan to determine if she does have a blood clot.  They want to do a Ct scan on the lung, we are worried about side effects to our unborn child, should we do it and what are the effects to our unborn child?
[|AI|]  Hi, Blood clot in lung is a serious condition, which can affect the well-being of your wife and can cause long term serious complications. Thus, it is very necessary that she has the CT scan as advised. Do not worry about side effects on fetus as CT lung, the field of radiation is away from uterus, and the chance of childhood cancer due to CT scan is very, very low at 1/1,85,000 exposures to CT. And it will be advisable to do the CT for maternal health as that would decide the further management of pregnancy as well. Hope this helps. Regards.
