Tomography, X-Ray Computed and Breastfeeding

Summary of use during lactation

X-rays used to obtain computerized tomography images (CT or CAT scans) are a form of electromagnetic radiation similar to light, but with a shorter wavelength. X-rays are present only during the short time that the image is being taken and leave no radiation or radioactivity in the body or in milk. X-rays have no known effect on the milk in the breast at the time of imaging.[1] No special precautions are required. For information on contrast media used with CT scans, see the LactMed entry for the specific contrast agent.
