Safety Limit For Ct Scans

For anyone who is concerned about the safety limit for computed tomography (CT) scans, it is generally harmless to propose a definite safety limit. One can have as many CT scans as required, provided the doctor thinks it is critical to diagnose or evaluate the progress of a disease condition. However, young children and developing babies in the uterus may be harmed by the radiation exposure from CT scans. This is why pregnant women, especially in their first trimester are not allowed to undergo CT scans.
