I am 10 weeks pregnant and i had a ct scan of my head done to rule out a cyst. The doctor covered me with the protective apron but i am still concerned about the baby being exposed.Will there be any harm to the fetus?
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.
When evaluating the risk of malformations due to exposure to radiation the dose of radiation received is very important. As a general rule, radiation exposure less than 5 Rads (Radiation Absorbed Dose) is not considered to have negative effects. Scattered radiation to the ovaries during a CAT scan to the head measures less than 1 millirad (or 0.001 Rads) per single scan, which is well below the 5 Rad cutoff (Maternal-Fetal Toxicology A Clinician? Guide, 3rd edition, 2001). Abdominal shielding with the lead apron should also reduce the radiation exposure.
