Women are usually able to breastfeed after a plain CT scan, but after an enhanced CT, resumption of breastfeeding after 24 hours is usually recommended due to the use of contrast media in the exam. Women can breastfeed right after a plain CT scan. Since CT scanning only contains a small dose of radiation and is well protected, the radiation does not accumulate in the body at this time, and usually does not affect milk secretion or milk quality, nor does it affect the baby’s health. However, if a breastfeeding woman has an enhanced CT scan, she needs to use contrast agent intravenously. Although the iodine contrast agent absorbed by the breastfeeding child is less than 0.01% of the maternal dose, it cannot be ruled out that it may have toxicity or metabolic reactions, and it is recommended that breastfeeding be performed 24 hours after the examination. Women can drink more water after the examination to promote the excretion of drugs, and breast milk can be expressed and discarded within 24 hours after the enhanced CT to avoid breastfeeding.
