Are chest x rays contraindicated in pregnancy?

No, chest X-rays are not absolutely contraindicated in pregnancy. However, they should be used only when the potential benefit to the mother outweighs the potential risk to the fetus.

X-rays use a small amount of ionizing radiation, which can damage DNA and increase the risk of cancer. The fetus is more sensitive to radiation than adults, so there is a small risk of developmental abnormalities if an X-ray is performed during pregnancy. However, the risk is small, especially if the X-ray is performed in the first trimester.

In some cases, a chest X-ray may be necessary to diagnose or treat a medical condition in a pregnant woman. For example, a chest X-ray may be used to diagnose pneumonia, tuberculosis, or heart failure. If an X-ray is necessary, the doctor will take steps to minimize the radiation dose to the fetus, such as using a lead shield to protect the abdomen.
