Final answer:
Lactating mothers who receive gadolinium-based contrast agents are generally advised to wait for 24 hours before resuming breastfeeding, although recent guidelines suggest that the risk to the infant is low and breastfeeding may continue without interruption.
Step-by-step explanation:
According to the American College of Radiology (ACR) Manual on Contrast Media, lactating mothers who receive gadolinium-based contrast agents can safely breastfeed their babies 24 hours before receiving the contrast agent.
Lactating mothers who receive gadolinium-based contrast agents should typically wait for 24 hours before resuming breastfeeding. This recommendation is based on the idea that gadolinium is excreted from the body relatively quickly, and waiting for 24 hours reduces the risk of the infant being exposed to the contrast agent. However, some recent guidelines suggest that the risk to the infant is very low and breastfeeding can be continued without interruption after receiving these agents.
