There is a certain impact of having a CT done just after implantation. As the CT examination process will be exposed to a certain amount of radiation, the fertilized egg is still in an unstable state when it is first implanted, and even if the fertilized egg is implanted, the embryo has not yet begun to develop, and it may be affected by the radiation, thus resulting in an abnormality. If CT is done during the implantation period, after the embryo is affected by radiation, with the gradual development of the embryo, fetal malformation may occur, which may cause serious miscarriage. It is recommended to pay attention to observe their own situation, need to carry out obstetric examination on time, to clarify the development of the embryo, if there is any discomfort, to go to the hospital in a timely manner, under the diagnosis of the doctor, to take reasonable treatment, so as not to aggravate the damage to the body, triggering the emergence of other diseases.
