X-rays during pregnancy should be used only when medically necessary, as exposure to radiation carries potential risks to the developing fetus, particularly in the first trimester when organ development is most sensitive. If an X-ray is required for an urgent medical reason, such as a fracture or a serious health concern, it can be performed with proper shielding to minimize fetal exposure. However, for non-urgent imaging, it is generally recommended to wait until the second trimester or later when fetal development is more advanced and the risk of harm is lower. Always inform your healthcare provider if you are pregnant or suspect you might be, so they can assess the necessity of the X-ray and consider alternative imaging options, such as ultrasound or MRI, when appropriate.
